PORTABLE WORKSTATION: This large tray is durable and lightweight. Keep your project organized in one spot as you move from room to room, or need to work on something else. ROOMY & SPACIOUS: Our tray measures 11.5” x 14.5” x 0.5” (29.2cm x 36.8cm x 1.28cm). This is an ideal size for designing, creating and still having room to hold other supplies. TRAY LIP: The Bead Mat Tray has a ½-inch lip. This is just enough to prevent spilling and keeping everything on the tray without being too cumbersome. BEAD MATS: Our soft padded and sticky bead mats (sold separately) are both designed to fit inside this tray. The foam like material keeps your beads from rolling around.
