Lily's HomeUnbreakable Acrylic Double Old Fashioned Whiskey Tumblers, Drinking Glasses for Liquor,Rum-Premium Shatterproof Glasses, ideal for indoor/outdoor,are reusable & crystal clear-13oz Set of 4

Nice glasses. It ok for outdoor party

Need a glass for use on a dock and boat. These are perfect rock glasses and could easily be mistaken for glass until picked up. Light weight, easy to hold not too large in hand. Probably will order another set for around pool.

I love it. Perfect inside outside without mentioning there durability to heat-cold.

EXCELLENT, larger whiskey tumblers that *look like glass* we use them in the hot tub - they are a bit wide and don’t fit in the cup holders- but that is a small issue because they are absolutely beautiful. We stroll across the street to the neighbors with them, and they said, “wow, bringing the good crystal?” We laughed and had to prove that they are plastic. The material refracts rainbows like real crystal. We’ve been washing them in our dishwasher, top rack, since August 3 (three months now) and they still sparkle and shine like new. (We do have a new high-tech dishwasher, FYI. Absoutely 5 stars.

Great for the RV, boat or by the pool. Look like glass and roughly the same thickness as crystal but safer where you wouldn't want to risk breaking a glass. I've used mine several dozen times and they look like new.
