Review on 🍶 Swig Savvy 17oz 4 Pack Multi-Purpose Real Borosilicate Glass Bottles - PBA Free, Leak-Proof Stainless-Steel Caps for Beverages, Smoothies, Oils & More by Brooke Nelson

Sometimes when I unscrew the cap, the small rubber piece inside the cap comes off. I rarely use a case to be honest, so this isn't a problem for me. I like the quality of the glass and the colors are beautiful. But they are slippery! You have to hold onto it tightly so that it doesn't slip out of your hands. I recently used one for iced coffee and the smell/taste didn't linger. That's nice. I also wash in the dishwasher.
