Frequently asked

How heavy is the Kailh BOX Red?

It's a light linear: roughly 40g to actuate and around 50g to bottom out, with a short 1.8mm pre-travel. That makes it quick and easy to press, which is why it's popular for gaming and rapid typing.

What makes the BOX design different from a standard Cherry-style red?

The BOX stem wraps around the contact leaf and rides on a POM cross, which cuts down on stem wobble and adds dust and moisture resistance. Many people find it noticeably smoother and steadier than a stock Cherry MX Red.

Do I need to lube the BOX Red?

No — it's pleasant out of the box thanks to the self-lubricating POM stem. A light hand-lube tightens up the sound and smooths the last bit of travel if you enjoy tuning, but it's optional.
