Iridescent glass - approx 150 x 150 x 3mm size sheet

Iridescent glass has colour on one side, the other side is a solid backing, so your base will not be visable through the glass.

It is flat on both sides so easy to cut.  you can use the pencil or pistol grip glass cutter for precise cutting or the 2 wheeled glass cutter.

We also have this colour iridescent glass in pre-cut into 15mm squares
