Thank you for viewing. This is a dark brown bag made of shrink leather with a textured grain. It seems like it could be used for a trip of about one night. There is no tag, so the material is unknown, but I believe it is cowhide based on the smell and weight. 【Size】 Width: Approximately 55cm Height: Approximately 33cm Gusset: Approximately 29 x 14cm Measurements are approximate, and some errors may occur due to amateur measuring. It was too large and heavy for me, as I am small. I bought it because I liked it, but I never used it. Are you interested in this item if you understand it is a used item? Returns and exchanges are not accepted, so please ask any questions before purchasing.
