Waterproof case. It seems to fit smartphones that are 16.5cm tall and 8.6cm wide. *Please refrain from ghosting in the comments.* Recently, there have been many people who ghost in the comments (leaving without indicating their intention to buy or not, or saying they will buy but never actually purchasing), which is very unpleasant. If three days pass without a response or purchase after I reply, I will delete the comment and block you. *Regarding price reduction requests (stating your desired price)* I will mostly decline, but if your price reduction request is around 5%, I will consider it positively. [Packaging Method] OPP bag + double bubble wrap + water protection [Shipping Method] Yu-Yu Mercari Bin (Yu-Packet Post) If there are no problems with the above, you can purchase immediately. Thank you.
