This is a Chums lunch bag. Made of a sponge-like material (neoprene) similar to a wetsuit, it's expected to have good cooling and heat retention properties. It's a vivid multi-color with the Booby Bird logo, making it cute. Size: Approximately 22 x 23 x 9 cm. Please allow for some error. It has been taken out of the bag but is unused and has been stored at home. It will be folded for shipping. Thank you for looking.
