Using this KittenBot Silicone Sleeve is a breeze. Just stretch the silicone gently and slide it onto your micro:bit board. The white bottom 'bumper' can be put on when you don't need to plug the board into the DragonTail breakout. When your micro:bit is inside the sleeve, you can wear it around thanks to the kitten ears. As for maintenance, simply use a soft, damp cloth to wipe it clean. Avoid using harsh chemicals as they might damage the silicone. Also, don't over - stretch the silicone to prevent tearing. That's all you need to know to keep your sleeve and micro:bit in great shape!
