MajorCrafts® 200pcs 7mm Cube Colourful Mixed Numbers Acrylic Beads with 4mm Hole Size

I bought these to identify different masks for my son to take to Uni. He wanted all his masks to be plain, so I made them in dark colours. They look good, but how to tell yesterday morning's mask from today's? I used these beads, threaded on to the elastic. The holes are large, which is why I bought them, and the elastic goes through them nicely.The reason for four stars, not five is that you get a random selection of colours and numbers, a bit like Smarties in a packet. I actually wanted more of some numbers, so I couldn't quite do the number order I wanted, which was 1 to 4 eight times (two beads on each mask, one on each side). I guess I was a bit unlucky with my numbers since there were 200 to choose from!The actual beads are quite small, and would be useful to identify keys etc.. if that is what you are looking for.
