Thank you for viewing! (⁠◍⁠•⁠ᴗ⁠•⁠◍⁠) It's quite large, so you can put in not only pens but also makeup brushes and various other items (*^^*) Pens are for photography purposes and are not included. Width: 21 cm Height: 8 cm Depth: 6 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 and shipped. Please understand about any creases. There is a smoker in the household. No pets.
