Drew made several different versions of his ultimate raked style marbles before he settled on some color schemes he wanted. This is a special one where he included the whole rainbow and WOW, is it stunning! The colors are set off against a white base, and then Drew used both opaque and transparent colors blended together to give the glass that unique and wonderful look that it has. This marble is a study in color play and glass flow! It is signed with the year '2008 EXP', meaning it is a one-of-a-kind experimental marble from 2008. Don't miss out on this extra special beauty!!
