Barrel 12oz Black

The quality is awesome! The rings are rubber and awesome to handle! Highly recommended!

The screw on lids and ability to seal the opening are as good as it gets!

First of all, I absolutely love the aesthetic. The barrel shape and wood grain is what got me (and my wife) to buy a pair. And performance-wise, they're fantastic. Keeps hot drinks hot or cold drinks cold for longer than you might expect, even if you've used vacuum-insulated drinkware before.

However, there are a few small design issues or oversights that prevent me from giving it a perfect score.

1) The inner diameter is so tantalizingly close, I can't understand why they wouldn't make it a fraction wider so that I could just slip in a 12oz can and have it double as a can insulator. Unless there's a patent issue of some kind, this seems like a squandered opportunity.

2) As others have mentioned, the 12oz capacity is just a little smaller than I would prefer. I honestly wouldn't mind it being scaled up proportionally to hold 14oz, 16oz, or 18oz.

3) The rubber rings around the outside are prone to slipping out of place. Not at all a deal breaker, just a minor annoyance when it happens.

4) The integration of the whale tail in the lid design is great... except it feels upside down. I kind of want the tail sticking up (like it's stick up out of the water) when you flip the top open or closed. Again, a missed opportunity to have it mimic the motion of an actual whale's tail.

Despite these issues, I'm happy with it, recommend it to my friends, and would buy it again.

Great addition to my whiskey collection stays super cold

Got these for coworkers Xmas gifts. Now I need to order a couple more for me.
