Blue Mason Jar 20 Oz Doubled wall Acrylic Cup with Straw - 2 Pack

These were purchased for drinking iced soda and nothing else. Easy enough you’d figure! Right? Wrong!! Cheaply made! Easily the worst I’ve ever purchased in this “Mason jar” style of mug. Out of a case of six, two so far have had the “silicone?” O-ring just drop out of the lid. Even after carefully lining the O-ring back into place it falls out over and over. I should not have to try and apply a bead of super glue to the inside channel of the lid. Leaks like a sieve!These are in a word GARBAGE! How bad are they? With all my Amazon purchases through the years, this is the worst review I’ve left and my only regret is that a ZERO star review is not an option. Were it an option that is what they deserve or perhaps a minus star review.Having soda running down your face onto your shirt isn’t how I envision enjoying a iced soda. DO NOT BUY THESE MUGS! Cheaply produced with no quality control junk, plain and simple.

As many other reviewers have stated, water gets trapped between the walls of the cup, when you wash the cup. I attached a photo to this review that clearly shows the water between the walls of the cup. The cup was brand new. This happened the first time I washed it, after the first time I used it. The cup was defective right out of the gate. I returned it, because it was defective.

Purchased this product to give away as party gifts. I decided to get this set because it met all the criteria I was looking for: clear smooth surface, no existing logo or words on the side walls, wide mouth, double wall construction, plastic (aka. kid friendly), and large enough to hold a good sized beverage... but in my gifting case, candy. It was perfect for my purposes, and enabled me to custom decorate them. I imagine these would be great for adults, older kids, and for gifts, parties, or to use at the office (like I'm doing with the extra one I made for myself).I'm thinking of buying some more for when we have small parties; I like how the double wall lets you be worry-free about excessive condensation, it's large enough to put regular ice cubes and easy to refill. I found it easier to use than regular glass masons and can hold more of the beverage (enough to fit an entire soda can with lots of ice). For parties, I'd recommend using a disposable straw just to ease the cleaning process, the straw that comes with the set is removable -- after all, who wants to wash handfuls of reusable straws? However, if it's just me, I do go through the trouble of washing my straw, as it is more eco-friendly and is easy enough to do if it's just the one or so.Compared to other sellers of similar products, this one was a good deal even with the cost of shipping since I ordered sets of 6. It came as described; packaged well to prevent breaking. There was also a slip of paper enclosed with the care instructions. Each mason jar came with 3 pieces: straw, lid, jar with handle. The construction is sturdy. The straw even had it's own packaging for cleanliness which was appreciated. As the seller picture suggests, there is a nub on the straw, which at first I didn't know what that was for, but I think it's so the straw doesn't easily slip out of the lid -- pretty thoughtful design.I'm so happy how the final product came out -- I'm attaching some photos. I'd recommend this product to anyone looking for a good gift or use for a party, especially if you're into DIY crafting. Even if you're not, I found the function of this set more than satisfactory and enjoy using it around the house and office for myself.

These are reasonable quality but seem overpriced. They do allow water into the space between outer and inner walls so you will see the view cloud up. They are light so that is a plus especially for older individuals. Overall not a bad product, but definitely could be put together better.

4 of the 6 cups have holes in them. When you wash them the space between the outer and the inter fill with water.

Glasses keep drinks cold. But they are not dishwasher safe. Put a few in the dishwasher, now they have separated somewhere and water has collected inside the double wall. I hand wash now!

Just got it in the mail and washed it because I planned on using it for iced coffee and there’s soapy water now stuck in the walls of the mug

We really like the Mason Jar drinking glasses. They met are expectations and are what we wanted. Thank you for your product.
