Blujellyfish Blue Glass Mosaic Tiles French Pattern Square Mosaics Sheets Iridescent Cobalt Blue Crystal Glass Ceramic Accent Wall Tile for Swimming Pool Kitchen Bathroom Backsplash (5 Square Feet)

These are absolutely gorgeous and really easy to work with. I used them in a DIY bathroom remodel for my backsplash and an accent stripe in the shower and both came out fantastic. In some light they are just a nice blue, in other light you get the reflective yellow, purple, oil slick look on the surface of some of the tiles (see photos). Has only been in place for a few days, so I can't speak to long term durability but no reason to think it'd be an issue. The mesh backing makes them easy to install with either mastic or mortar, and individual tiles can be peeled off and placed singly for when you have a different dimension to account for. The size is a good match with a standard 12" tile. One thing to consider (that I did not!) is the thickness is less than typical wall or floor tiles, so you either will have a transition in the grout, or you need to build up the level with mortar to make them flush. I left it with a transition and it looks fine on the wall.

We use this as a section of floor tile in the bathroom after removing a sink that left a huge empty space, and this was a gorgeous accent for the ocean waves painted on the walls

This time worked perfectly in our bathroom remodel. Used it for accents around our bath tub and sinks.
