Works For Me!!

More sturdy than I thought. I bought 2. I drink a lot of water and didn’t want a bulky cup. It keeps my drinks cold, I’m a big fan of cold drinks with ice- or even just ice sometimes, and this tumbler works out perfect for me. Also, if I knock it over somewhere it doesn’t spill (much if anything). Just remember HAND WASH ONLY. NO DISHWASHER and you’ll be just fine

Perfect bottle got water

I found these on clearance, only bought 2, I love these plastic glasses. Each holds 1 bottle of water and couple of ice cubes. I wanted to get more in case they broke by dropping it, so I ordered a case

Mainstays Clear Plastic Tumbler with Screw Top Lid

I got the 5 pack of 20 oz clear shatter proof Plexiglas. I love the screw tops lids with clear plastic straws. I feel more confident when caring my cold beverage anywhere because the screw top lid does to come off until I unscrew it. So far, there have been no fear of accidental spills, and I love being able to see when my drink needs a refill. For the price I could afford to take the chance and tries them. No regrets and I'm buying more now!
