Keeps beer cold!

Company originating from Vancouver, BC. I did a test: put a chilled beer in the holder and left it at room temp. After 1 hour my beer was still cold!! Has a bottle opener and soft silicone base/handle, which is nice because it can be put on any surface without scratching. Coronas fit perfect! Does not fit all bottles, their site has a full list of the ones they fit.
The silicone cosy comes off easily to clean.
