What you’ve got there is a purpose-built glitter catching tray designed for tumbler makers, especially those working with epoxy and fine craft glitter.

It’s a rectangular tray with a raised outer frame that helps contain loose materials and prevents spills from spreading across your workspace. The standout feature is the honeycomb (hexagonal) grid surface on top. This grid acts as a filter layer—when you sprinkle glitter over a tumbler, the excess falls through the hex openings instead of piling up on the surface.

Beneath that grid is a solid base layer, which collects all the fallen glitter. This makes cleanup and reuse easy—you can simply lift or tilt the tray and pour the collected glitter back into a container without waste.

The design is practical and efficient:
• Even distribution: The open grid prevents clumping and lets glitter fall naturally.
• Material recovery: Minimizes waste by catching excess glitter.
• Cleaner workspace: Keeps your table free of stray particles.
• Reusable workflow: Ideal for repeated tumbler coating sessions.

Overall, it’s a smart tool that combines precision application with mess control, making it especially valuable for anyone doing detailed or high-volume tumbler customization.
