New/Old Stock 14 x 12mm Highly Polished Window VASELINE/URANIUM GLASS BEADS w/Matte Edges- originally from the Czech Republic. These are from my personal collection which began in the latter part of the last century. Despite their age, they are in pristine condition. The hole is a standard +/- 1.0mm. Easy to string, wrap or whatever technique you would prefer to use for your projects. There are a number of lots available with Five (5) beads in each lot. They’ve been black light tested and are guaranteed to fluoresce a brilliant neon green under Ultra Violet light (390 - 405nm preferably).
