The sliding lock top on my mom’s 30 oz double walled stainless tumbler in an action video-
So many people telling me they can’t find the link.
So here it is- The worlds greatest invention that everyone I know who got one absolutely loves theirs and can’t believe they’ve lived this long without-
Here’s the link to get one with two different style lids, one open and one with a locking lid- Buy it on Amazon by clicking this link $16.99
They are just like the YETI ones that sell for three times as much and only give you the one non-locking lid. $16.99 is like stealing this 30 oz tumbler!
