More odds and ends! These flat little buttons come in a mix of soft colours, along with some more strident yellows, reds and blacks (there are perhaps slightly more red ones than you would expect in a well-balanced colour blend, but the effect isn’t very noticeable. I’m just trying to be critical on your behalf). All the tiles are opaque glass, and a few have an iridised finish. Each bit measures 18mm diameter, and is 4mm thick, so will sit happily alongside all your other tiles. The tiles are supplied in 250g bags, which contain around 110 pieces. The bottoms are completely flat with a few indentations to help your adhesive stick.
