SNOOPY This is a stainless steel water bottle featuring illustrations of Snoopy and cookies. It holds 500ml. It has a temperature sensor, but the temperature display only worked twice, possibly due to the battery. Therefore, it's practically new. I bought it for my child's milk, and it was mentioned that it could be used if the battery was replaced, but I didn't bother trying. I haven't put my mouth on it. I've only washed it, so there are no major stains, but there might be something I haven't noticed. I can't guarantee the sensor will work, but I think it should be fine as a water bottle. There is no box, so I plan to wrap it in bubble wrap and send it in a regular envelope or something similar. I'm new to Mercari, so I'm not used to shipping, and it may take 2-3 days, but I will try my best to ship it as quickly as possible. I would like to sell it to someone who understands.
