Ravensburger Sort and Go Jigsaw Puzzle Accessory - Sturdy and Easy to Use Plastic Puzzle Shaped Sorting Trays to Organize Puzzles Up to 1000 Pieces, Blue
In my opinion these trays are a must have. I have two sets and will probably be purchasing another soon. They help separating by color, border or which ever way you prefer.
So if you like some order in the chaos of completing a puzzle these are essential!
