This is a small seat bag made by Goldwin. Please refer to the measuring tape in the photos for the size. I purchased this item used and used it several times for day trips. It's very easy to use with the X-type fixing belts. Everything in the photos is included. Please make your decision based on the photos, and consider purchasing if you were looking for this item. Regarding shipping, it will be shipped in simple packaging such as cardboard. Thank you for your understanding. I apologize, but as stated in my self-introduction, my work is quite irregular and I often have short business trips, so it may take up to a week to ship depending on the time. If you need the item shipped urgently, you may want to refrain from bidding. Also, this is not a new item, but a used item. Please make your decision based on the photos and consider purchasing on a no-claims, no-returns basis.
