Large capacity, thin and light! It's a backpack. It folds up compactly, so you can take it on trips and use it expanded. It won't take up much space and I think it will be useful at your destination. I bought it for sports. I bought this instead of a drawstring bag because the shape is very similar! Even if you put in a change of clothes, drinks, shoes, and snacks, there's still plenty of room *⸜(* ꒳ * )⸝ The diameter of the bottom is about 29-30cm. It's three-dimensional, so it's difficult to measure, but for reference. The vertical length is about 44cm. It holds a lot and is a very useful backpack♡ I wanted a unique backpack, different from others♡ I passed on backpacks that are heavy themselves because they make my shoulders stiff! Lightweight, decent durability, and high design! I chose this based on these three points❗️ Finally, I've included a close-up of the print, and there's an alphabet logo❗️The design is❗️ It's super stylish⭐️ It's like a drawstring bag, and the part you pull to tighten it has a shocking pink string, which is really cute♡ If anyone is looking for a unique backpack, I highly recommend it (⁎⁍̴̛ᴗ⁍̴̛⁎) I don't know the brand name, and I've forgotten it myself, so I haven't written it in the product name. I'll write it in the product name when I remember. I will compress it when shipping, please understand m(_ _)m Please be sure to read my profile♡
