This is a Gherardini bag. It does not have a strap or a dust bag. I purchased it used, but it's still in good condition, and I haven't used it much. The inside has a pattern and is lovely. The handles are also clean. Please refer to the images for the size. There is no shoulder strap. There are metal fittings on the front and back, so I think a strap can be attached here. It's a reliable bag, perfect for a day trip. It easily fits a long wallet, a water bottle, a smartphone, a towel, etc., and the bag itself is relatively light. I will ship it via anonymous Mercari delivery. However, even if it's listed as Yu-Yu Mercari delivery at the time of listing, I will use whichever Mercari delivery service allows for faster shipping at the time, so it may be switched from Yu-Yu to Raku-Raku, or vice versa. Thank you for your understanding. I will post the weight later. It will be shipped folded. I will accept comments.
