GLASS TUMBLER 2P SET GY MM370

I bought this to drink with my husband every night. It's cute, light, and the perfect amount goes in. I use it as a beer glass.

To be honest, it's a bit heavy for a glass. It doesn't spill easily, but when you're washing it, the bottom is heavy, so if you lift the drinking spout with your hands, which are covered in detergent, it's easy to slip and drop it in the sink a few times. I'd like you to improve it so that it doesn't slip even if your hands are wet. The drinking spout is easy to drink from because the glass is thin.
