This is a packet of 275 20mm irridescent vitreous tiles to add to your collection of mosaic bits and pieces. You will get 25 of each shade lovely solid colours with iridescence white, soft pink, pale green ,pale lilac ,baby blue , black, purple, orange, yellow, green and turquoise blue . I have taken them off the backing to show the irridescence. They will come on paper which you can soak off in warm water for 5 mins.These are perfect for doing Martin Cheek style mosaics as they require very little cutting. They can be easily cut with the wheeled mosaic cutters. The colours are available separately let me know how many you would like and I'll list them for you. If you would like a full sheet(225tiles) of a colour listed just ask I can send two sheets rolled in this pack. I am happy to combine post
