What's a Group Buy?

A group buy (GB) is a pre-order system used by the custom keyboard community. A designer creates a keycap set, gauges interest, then opens orders for a limited time. Once the window closes, the set goes into production.

The typical lifecycle:

1
Interest Check (IC)The designer posts renders and collects feedback. No money changes hands.
2
Group BuyOrders open for 2-6 weeks. You pay upfront to your regional vendor.
3
ProductionThe manufacturer produces the set. This takes 3-18 months depending on the manufacturer.
4
ShippingSets ship from the manufacturer to vendors, then to you.
5
ExtrasSome vendors order extra units. These go on sale after delivery, first-come first-served — no wait.

Group buys exist because custom keycap sets are niche products — manufacturers need a minimum order quantity (MOQ) to justify a production run.

Keycap Profiles

The shape and height of each keycap. Different profiles feel different to type on.

Cherry

Named after Cherry, the switch manufacturer. Sculpted rows with a low-to-medium height. The most widely available and popular profile for custom keycaps.

SA

Tall, sculpted, retro-style profile. Spherical top. Deeper sound than Cherry.

MT3

Tall sculpted profile with a deep dish. Similar feel to SA but with scooped tops.

KAT

Medium-height sculpted profile. PBT plastic. Made by Keyreative.

DSA

Low, uniform (non-sculpted) profile. Same shape on every row.

XDA

Uniform profile with a wider, flatter top surface than DSA.

OEM

The profile found on most stock keyboards. Sculpted, medium height. A safe starting point.

DCS

Similar to Cherry but slightly taller. Made by Signature Plastics.

MDA

Medium-height sculpted profile with rounded tops. A hybrid between Cherry and SA.

KAM

Uniform profile with flat tops and thick walls. Made by Keyreative.

Signature Plastics

US-based manufacturer. Makes SA, DSA, and DCS profiles. Also known as SP.

Domikey

🧱

Materials

What the keycaps are made of. Each material has a different feel and sound.

ABS

A smooth, durable thermoplastic. Allows vibrant colors and sharp doubleshot legends. Develops a polished "patina" with extended use — some love the feel, others prefer PBT.

PBT

A harder, more textured plastic than ABS. Retains its matte texture over time and produces a deeper "thock" sound. Legends are typically dye-sublimated.

POM

Polyoxymethylene — dense, smooth plastic. Rare in keycaps. Deep sound signature.

doubleshot

Two separate plastic molds fused together — legends never fade because they're a separate piece of plastic.

dye-sub

Dye-sublimation — legends are heat-printed into the plastic. Durable but limited to darker-on-lighter colors.
