Puzzle Piece Organizer Tray with Lanes (Stackable)

Modified version of the Stackable Puzzle Piece Organizer Trays by PanacaGuy. Adds 2 plates with different lane segments.

On the many lane model, the first 4 lanes are designed to be loosely one piece wide; yet narrow enough to prevent pieces from rotating. The extra space on the right is for holding pieces with looser organization.

There is also a 50/50 split plate for simpler organization of pieces.

I found these invaluable when working on the One Piece mosaic puzzle, where shape sorting was necessary to make any progress.
