Thank you for viewing. This is a KELTY tote bag. I think I threw away the shoulder strap because I didn't need it. It has only been used for a short time, 1-2 times, and is in very clean condition. The inside is very sturdy and waterproof. Please refrain from purchasing if you are concerned as this is a used item. 【Size】 Width: 41cm Height: 32cm Depth: 13cm
