This colorful replacement top case is designed specifically for the KUL ES-87 Tenkeyless Mechanical Keyboard. Manufactured to Keyed Up Labs exacting quality requirements, they're available in several carefully selected colors to bring a little bit of color and class to your working or playing environment! Special note on individual colors: Our white is bright! Also, all non-white colors are made with a metalized plastic mixture (no paint!) and will exhibit some color shifting and swirling effects depending on the direction of ambient light. Some dis-assembly of your ES-87 is required, but only a screwdriver and a few minutes of time should be necessary. This will not void your warranty!
