Review on 🐇 Clear Freezable Rabbit Beverage Glasses by Peter Tennant

Good glasses, but not worth €15. Maybe $5 each, but they're just like any other jar you put in the freezer to chill, but with nice packaging to help your hands. The thermodynamics of the heat exchanger don't magically change, there's too little liquid between them to make 12 ounces of liquid that much colder. But it seems to keep the liquid cooler for about 15 minutes. Also, 1 hour in the freezer was too short to actually freeze the jar, it took over 2 hours to actually freeze the coolant and the jar.
