This tray has sturdy side walls that you can roll against. We like leave one wall down and side toss our dice into the tray at a low angle so they hit the back wall, kind of like a mini craps table.
The snaps are positioned so you can even fold it up in reverse with the leather side up. Just fold the snaps inward and now you're rolling onto the leather side!
Features:

• Easy to carry to games, easy to setup, small so it doesn't dominate your table!
• +9 against metal dice damage to wooden tables
• Quiets loud dice rolls on plastic tables
• Keeps dice from flying off the table or hitting your minis
• High quality materials, strong enough for metal dice
• 10.5 inches across when flat, 6 inch rolling surface in "Tray" mode
• Fits easily into backpacks and folders
