Rockbros Cooler Backpack 20L - 48 Hour Cold Retention

ROCKBROS Cooler Bag, Backpack Style, 20L, 48-Hour Cold Retention

Purchased on Rakuten and used about 5 times.
There is some scuffing on the bottom, but I don't see any other noticeable scratches.

It has excellent cold retention and, being a backpack style, I think it would be useful for camping and leisure.
The included grease will also be provided.

■ Precautions for Use:
1: Cold retention performance varies depending on the usage environment, temperature, frequency of opening and closing the lid, etc.
2: The zipper is stiff to ensure airtightness. If it is difficult to open, apply zipper lubricant oil evenly with your finger and open and close it a few times to break it in.
3: To prevent leaks, close the zipper completely to the end.
4: Avoid using with sharp objects. This may cause damage to the insulation.
5: Avoid using the bag when it is laid on its side or upside down.
6: You may notice an odor immediately after opening. Wash and dry in a well-ventilated shaded area. If the odor persists, store with the lid open in a well-ventilated shaded area for a few days.
7: Avoid using detergents. Wash with water, dry thoroughly, and store in a well-ventilated place.
