① Manufacturer: 【UPPERWEST】 Upper West This is a bag from the UPPERWEST DRY BAG series, made with tarpaulin material, which is highly waterproof and used for tents and yacht sails! I think it's perfect for sports and outdoor activities. ② Material: 【Tarpaulin】 Tarpaulin is a material made by sandwiching polyester fibers with synthetic resin, and is often used for tent roofs set up at athletic meets, etc. As the name comes from "tarpoulin" (waterproof cloth), it is a strong material that is resistant to rain and dirt. 【Highly waterproof】 It will be a great companion for everyday outings, as well as for the sea, mountains, and touring. ■ Material: PVC tarpaulin ■ Size: Approximately 27 x 18.5 x 7.5 cm It's an old item, but it's almost unused, so I think it can still be used. Thank you very much.
