*IMPORTANT* Please note that the Milky Boba housing has been discontinued due to discoloration concerns over time. The all-black housing that replaces it does not experience this issue. If you are interested in purchasing the Milky U4 switches, you can find them available for purchase here. Thank you for your understanding.

This is the critically acclaimed Boba U4 Silent Tactile Switches designed by Gazzew himself. Highly rated within the keyboard community, they feature a prominent rounded silent tactile bump. Thanks to the stainless steel springs, they give you the quietest typing experience, without the accompanying clicks and clacks of regular tactile switches.
