These work very well for the MBK keycaps I also bought here. The square "loops" on either end are definitely fragile, as other folks have noted. I was using precision tweezers to lift and very carefully fit them over the keycap stems, but some of them still snapped. Fortuntately, I only needed 42 out of the 48, so I still had a couple extra at the end. Buy another set if you need exactly 48. Still recommend!
