I used it once. There's Velcro on the back of the lid, so when you open the lid completely, the Velcro attaches, and it opens fully. This is very convenient when cooking because the lid doesn't get in the way, and it doubles the space to put things. The inside is made of aluminum foil, so even if soy sauce or sauce spills, you can wipe it off quickly. Also, because it's aluminum, it reflects radiant heat, so I think it also has cooling power. Approximately 12.5 x 8 x 9.5 (height) cm I will ship it folded or slightly compressed. Camping Seasoning container Nalgene Wide Mouth Round Bottle
