This is a small item storage unit with 32 trays. There are trays numbered 1 to 31, and one tray without a number. [Calendar Shelf] How about using it as a shelf to organize small parts? Overall: Approximately 31cm wide x 26cm deep x 41cm high. Tray inner dimensions: Approximately 13cm wide x 24cm deep x 2cm high. Weight: Approximately 6.3kg. The trays have minor scratches from use. Please check the photos. Personally, I used it to store small items such as stationery, batteries, postcards, and stamps. All trays can be removed smoothly. Please consider this item with the understanding that it is a used item stored at home. Thank you for looking.
