Thank you for viewing! (⁠◍⁠•⁠ᴗ⁠•⁠◍⁠) It's compact but has a gusset, so it can hold a lot. It held 15 pens (⁠。⁠•̀⁠ᴗ⁠-⁠)⁠- Pens are for size reference only and are not included. Top width: 20 cm Bottom width: 17 cm Height: 6 cm Gusset: 4 cm Uses a 20 cm zipper. Interfacing is used on the outer fabric. The opening is closed with a sewing machine because I'm not good at hand-sewing. It will be folded for shipping. Please understand about any creases. There is a smoker in the household. No pets.
