(New, Unopened) Essential for Beach Trips! Neutropical Air Mat - Blue Dolphin Design

Several years ago, when my children were still in the lower grades of elementary school, I bought this with the intention of taking them to the beach or pool during summer vacation. For some reason, I never opened it and it ended up being stored away in the storage room.

I tried searching for it, but couldn't find the same item and therefore couldn't get any information.

Based solely on the packaging...
The product name is NEW TROPICAL Air Mat.
Country of origin is China, and the size is 68cm x 178cm.
Purchase location, manufacturer/distributor, retail price, quality, etc. are unknown.
No. 00191... that's all.

The only other visible information is the warning text that is now mandatory to be printed on products (Image 4).

However, I believe the material is likely vinyl.

Regarding shipping methods, given the size, it will likely be Yu-Pack via YuYu Mercari便 or Takkyubin via RakuRaku Mercari便.

I cannot fulfill requests to upload images of the product after opening it. Please make your judgment based on the existing images.

As it is an unopened, unused new item, I don't expect there to be any scratches or dirt. However, since I have never actually inflated it, please understand this circumstance.
