Review on 🥤 Atlin Tumbler [30 oz. Double Wall Stainless Steel Vacuum Insulation] - Black Travel Mug [Crystal Clear Lid] Water Coffee Cup [Straw + Handle Included]: Ideal for Home, Office, School, Ice Drink, Hot Beverage by Carrie Green

I have researched and purchased many of these items and this is the ONLY ONE that 1. TOTALLY RELIABLE leaks even if you knock it over, 2 y iced coffee lasts all night with ice , which swims in it at least 12 hours, if not 24 and 3 hours. Durable, unbreakable, cleans up as easily as a fork and comes back in perfect condition. I use a weird plastic pen all the time that I've never seen before. it's a hit. I actually bought two, one for coffee, one for water, and placed them side by side everywhere I work (and in the car - they fit in cup holders that many water bottles don't have). Finally, it comes with a small loop handle for cyclists and backpackers, which I can't use as I can't see where it attaches to the exquisitely smooth surface, but since I'm not at all interested in movement, I don't care. .
