Brand new, unused item. It's a very cute Little Twin Stars water bottle. The packing is secure, so the contents won't leak. I haven't used it, but it seems to have decent cold retention. It holds 350ml. The cap is easy to open and has a strap, so you won't lose it. The opening is wide enough to easily clean with a 100-yen store bottle sponge. How about this for your child's water bottle?
