This is a small part storage tray with a lid. As an amateur watchmaker, there is a need for sorting and storing very small parts. I needed a tray with a translucent lid to protect parts from dust and debris after they are cleaned. The tray has 18 30x30mm cells, 3 30x62mm cells, 1 62x62 cell and 1 62x128 cell. The tray is 12mm tall and each cell is 10mm deep and overall it is 201mm square.
