This is an insulated lunch box with an adjustable strap by Sanne . The strap is thick so it is not uncomfortable on my shoulder. There is plenty of room for 8 cans or 6 bottles, there is lots of room for a large lunch. The lunch box has a zipper pocket on the front, great for utensils and napkins. This comes with a great colorful pattern and there many others to choose from. This is made for reusable frozen blocks not ice as when the ice melts the water escapes. The top of the lunch box closes by a zipper. This lunch box costs: $ 13.99 https://www.amazon.com/dp/B071P9CX3Z/ref=cfb_at_prodpg
