These tiles are a dark blue foil. The tops are smooth, with the foil under the glass. These are 20mm (3/4") and are 4mm (1/6") thick.
This is for 25 tiles.
With the foil, be sure to test your adhesive to verify it won't affect the foil. Likewise, these should be used for interior, dry installations out of direct sunlight.
These tiles may be cut but the backside sometimes is damaged if your nippers are not sharp enough. To avoid this problem, ensure your cutting blades are sharp.
These came on a plastic sheet and may or may not still be attached to that sheet when you receive them.
