Twenty-two mini sheets (each with twenty-five tiles) - a sheet of each one of the plain colours made by Cinca.  That's a total of 550 tiles, each measuring 2.4 x2.4cm.  Used together, these tiles will cover an area of approximately 58cm².  The tiles come face-mounted on backing paper, and will need to be soaked off.  An economical way to increase your palette and experiment with all the colours offered in this wonderful range. IMPORTANT! You should always wear a mask and eye protection when cutting mosaic materials.
