Thank you for viewing! (⁠◍⁠•⁠ᴗ⁠•⁠◍⁠) How about using it for cosmetics or small items besides pens? (ㆁωㆁ*) The pen is for size reference and is not included. Width: 15.5 cm Height: 5.5 cm Depth: 5 cm Uses a 20 cm zipper. Interfacing is used on the outer fabric. The opening is sewn with a sewing machine because I'm not good at hand-sewing. It will be folded for shipping. Please understand that there may be creases. There is a smoker in the household. No pets.
