To Sellers: I put a lot of time and effort into creating clear and easy-to-understand product descriptions. If you are selling the same product, please refrain from copying and pasting the text. Recently, I've noticed many people using the exact same text or slightly modified versions for their listings (after liking the product and then copying the description). I won't contact you directly, but it's not a pleasant experience, so I hope you'll consider this with some discretion. Brand new, unused! This is a Thermos mug water bottle that keeps drinks cold or warm for a long time. It can be used in the summer, of course, but also for warm drinks in the winter, so you can use it for a long time.

This item is stored at home, so there may be some scratches, dents, or dirt. Thank you for your understanding. Regarding returns, I will only accept them if there is a shipping error on my part. *In mid-October, there was a complaint about the color of the product. I carefully send out brand new, unused items. I will not accept returns or exchanges for reasons that do not match the image! No need to contact me before purchasing. If someone purchases the item while I am responding to comments, I will prioritize the buyer. For shipping, I will use "anonymous shipping" because I want to prioritize safe transactions. If a delivery notice is issued, please promptly request redelivery from the delivery company. (To prevent the return of the product) Thank you!
