Haimu Mulberry Tactile

Haimu Mulberry Tactile is a collaboration switch designed by YG Studio and manufactured by Haimu, built around a stainless-steel insert set into a long-pole stem. Sources agree the insert gives bottom-out a brighter, metallic ring than an unmodified stem, paired with a pronounced, rounded tactile bump felt early in the stroke and a snappy spring return.

It ships factory lubed and is sold under the Mulberry name through several third-party switch retailers rather than an official storefront.
