These are great value bags of loose vitreous glass mosaic tiles in a random mix of colours. Colours will vary. The tiles are normally 20mm x 20mm x 4mm. The vast majority of these mixes are made up of Chinese glass tiles which are best cut using the Leponitt wheeled cutters. They can be cut with the standard nipper but the results can be variable. We sell these mixes in bags of various weights starting from £5.00 for 700gm which is roughly equivalent to a full sheet of glass mosaic which should cover an area of 32cm x 32cm approximately. You can also buy 3 x 700gm bags for £12 as well as 5kg - £25.00, 10kg - £45.00 and 20kg - £85 . The more you buy the cheaper it becomes !
