Custom Brass Kaleidoscopes: How a Commission Works
Updated: Aug 30
Lab Notes - Studio Yabaye · by Roi (ROCCO) Ramon
A custom brass kaleidoscope commission is a run built to one specification you approve before production starts. In practice it means choosing three things: the instrument, the marking, and the quantity. Everything visible on the outside is open to change. The optics are not, because mirror angle and tube length are what make the pattern work, and there is no version of those that can be adjusted for branding without degrading the instrument. This page sets out what can be changed, what cannot, and what happens between the first email and the delivery.
Three levels of custom
The word covers three different jobs with three different costs, and confusing them is what makes quotes hard to compare.
Level | What changes | Typical use |
1. Marked | An existing instrument, engraved with a name, logo, date or message | Recognition gifts, closing gifts, anniversaries |
2. Specified | Instrument built to chosen dimensions, finish, object cell contents and packaging, then marked | Corporate runs where the piece has to match a brand palette |
3. Designed | A new instrument developed for the commission, drawn and prototyped before the run | Awards, anniversaries, installations, single sculptural pieces |
Most corporate commissions are level 2. Level 3 is a design project with a design timeline, and it is priced as one.
Custom Brass Kaleidoscopes: What Can Be Changed, and What Cannot
This is the part most suppliers leave vague, so here it is plainly.
Open to change
Length and diameter of the body, within the range that keeps the eye relief comfortable.
Finish: polished, brushed, or left unlacquered to develop a patina with handling.
Object cell contents. The colour palette inside the instrument can be selected, including to sit near a brand palette. This is the single most effective way to make a run feel specific to a client, and it is the one most people never ask about.
Engraving: logo, name, date, message, serial numbers.
Packaging and presentation.
Fixed by the optics
Mirror angle. The angle sets the pattern, and the accepted configurations are the ones that produce a clean symmetrical field. An angle chosen to look distinctive on a drawing produces a broken pattern in the hand.
The relationship between tube length and mirror width. Change one without the other and the pattern stops reaching the edge of the field.
Mirror quality. There is no budget version of this that is worth shipping. It is the first thing a recipient notices and the only thing that cannot be fixed afterwards.
The reasoning behind all three is set out in The Architecture of Light: How a Brass Optical Instrument Is Built.
The five stages of a commission
Brief. Quantity, occasion, recipient, deadline, budget range. Five lines is enough to start.
Specification. We come back with the instrument, the marking layout, the finish and the cell palette, priced. This is the document that gets approved, and nothing goes into production before it does.
Proof. The marking layout is proofed and approved before anything is cut, because brass and screen render lettering differently and a logo that reads on a monitor does not always read on a curved metal face.
Production. Machining, mirror calibration, assembly and marking. Each instrument is checked by eye before it is packed.
Delivery. Shipped worldwide, individually packed, ready to hand over. Production runs to a maximum of 21 days from the approved specification, depending on quantity and requirements.
Engraving, and how brass behaves
Marking is cut into the brass with a fiber laser, not printed onto it. The practical consequences are worth knowing before you send artwork:
Depth is permanent. A cut mark cannot wear off, and it will still be legible after decades of handling. Printed and pad-applied marking will not.
Fine detail has a floor. Very thin strokes and small text close up on a curved brass surface. A logo that works on a business card may need a simplified version for a 3 cm curved face, and we will say so rather than ship something illegible.
Curvature limits the area. Marking sits cleanly on a defined band around the tube. Artwork that assumes a flat rectangle needs re-laying out.
Contrast comes from the cut, not from ink, so the mark reads as part of the object rather than as a sticker applied to it. This is the difference recipients register without being able to name it.
A commission that shipped
In 2025 we produced 75 engraved brass kaleidoscopes for Coldwell Banker Caine, built to a single specification and delivered as one run. The relevant detail for anyone considering a commission is not the number: it is that 75 instruments came off the same specification with the same mirror calibration, which is the part that is difficult and the part that decides whether a run looks like a set or like 75 approximations of one.
What a corporate gift has to survive
The measure of a corporate gift is not what the recipient thinks when they open it. It is whether the object is still on their desk two years later, because that is the only period in which it does anything for the giver.
Most corporate gifts fail that test for a structural reason: they are consumable, they are branded more loudly than they are useful, or they have no reason to be picked up twice. An optical instrument is picked up because looking through it is the entire point, it works without instruction, and it is quiet enough to sit in a room where a branded object would not be tolerated. The engraving is read by whoever picks it up, which over two years is a great many more people than the recipient alone.
What we need in order to quote
Five things, and a quote can be issued from them:
Quantity, or a range. Commissions start at 10 pieces.
The occasion and who receives the pieces.
Deadline, including whether it is fixed to an event date.
Artwork or the text to be engraved, and whether a logo is involved.
Whether the cell palette should reference a brand palette.
Production runs to a maximum of 21 days from the approved specification. Deadlines fixed to an event date should be named in the first email, because the specification and proof stages sit before production begins.
Frequently asked questions
Can a kaleidoscope be engraved with a company logo?
Yes. Logos are cut into the brass with a fiber laser rather than printed. Very fine strokes and small text may need a simplified version to stay legible on a curved brass surface, and the layout is proofed before production.
Can the colours inside the kaleidoscope be matched to a brand?
The object cell contents are selected as part of the specification, so the palette inside the instrument can be chosen to sit near a brand palette. It is the most effective way to make a run feel specific to one client, and the least requested.
What is the minimum order for a custom commission?
Ten pieces. Single engraved and personalised instruments are available through our Etsy shop instead, without the specification and proof stages.
How long does a commission take?
Production runs to a maximum of 21 days from the approved specification, depending on quantity and requirements. Deadlines fixed to an event date should be raised in the first email, because the specification and proof stages come before production begins.
Can the mirror configuration be customised?
No, and this is deliberate. Mirror angle and the relationship between tube length and mirror width are what produce a clean symmetrical field. Changing them for visual distinctiveness produces a broken pattern, so the customisation happens in the body, the finish, the cell and the marking instead.
Do you ship internationally?
Yes. Instruments are hand-machined in our studio in Lehavim, Israel, and shipped worldwide, individually packed.
Can I order a single personalised piece rather than a commission?
Yes. Single engraved and personalised instruments are sold through our Etsy shop. Commissions of multiple pieces to one specification are handled directly.
