Review on ☕ 14oz Primula Coffee Mug: Vacuum Insulated Stainless Steel with Leak-Proof Lid - Double Wall Travel Tumbler Cup Thermos to Keep Drinks Hot or Cold (Teal) by Breanna Homack

I rarely find a product that really deserves 5 stars, but this is one of them. Fully sealed and I flip it over the sink every time just to check. I don't know anything about the long-term durability of the seal. What really wowed me through and through were the instructions that specifically point out how to get the lid to be used with either the left or right hand. It's the little details that can really make a product go the extra mile. Impressed and would recommend to others. I wish they also had a version with no handles or a little thinner but larger to fit more cup holders in the car.
