I purchased this on AliExpress. I bought it for its quietness, but it turned out to be the wrong type for my keyboard, so I'm selling it. Purchased as a set of 90 (※I haven't counted to confirm if there are still 90 after purchase.) Please be aware that there may be initial defects due to being an imported product. ⚠️The cylindrical case will not be included due to packaging constraints. 90 Kailh Deep Sea Mini key switches
