What on earth are these things called? I need some sturdy gadgets that will identify a key (or keys) and I want about 70 of them. I have some at home that are ideal. Translucent plastic in various colours,
70x35x10mm so they will hold a decent sized identifier of card or paper, also big enough not to get lost in a pocket. I've googled for ages and can't find anything similar. Any ideas please? Nick.
