's meager instruction is that there is a one inch indentation on both sides from the bottom of the case under the decals. On the front, I tore off the sticker half an inch from the top and glued both parts of the sticker, leaving the half inch exposed at the bottom. On the other side I made a sticker. Squeeze both ends and the case will slide out. You can also score Decaleon from the front. I just want all the printing on the sticker. I didn't rate durability as I only have drill bits. I know Bosh is a good product
