Sticky Bead Mat XL Our Sticky Bead Mat XL is double-sided, and made of sticky silicone. One side is indented with U-shaped channels like a traditional bead board, and holds beads and small parts in place while measuring and arranging before stringing. The other side is flat, for use as a bead board! Both sides are marked with measurements in both inches and centimeters. Best of all, it's flexible and can be rolled up for travel. Measurements: 12-1/8" x 8-3/4" Why do I need this item? This Sticky Bead Mat XL is portable, works great for holding beads in place, and cleans easily, simply by rinsing with water.
