Organizers & Trays

Manga Slipcase for 135×15×215mm Book
A protective slipcase sized to slide over one specific book/manga volume (135mm deep, 15mm thick, 215mm tall), so it fits snugly instead of using a generic case that's the wrong size for this exact volume.

A shallow ribbed tray (185×90×12mm) for organizing small flat items, with 5 evenly-spaced parallel ribs dividing the tray into compartments.
