Plastic Juice Bottles with Caps 12Pcs -12oz Reusable Juice Containers with Tamper Proof Lids Black - Clear Bottles for Juicing Milk Smoothie Drinking and Other Beverages Christmas Gifts

There are some tricks to these bottles but if done correctly, they work very well. First, tighten the cap all the way down to break the ring seal on the cap and then leave that ring on there. See steps 1 through 4 on the product page. If you do not do this you will likely leak. However, if done properly, the cap seats well and you can feel it do so use after use. None of the 12 bottles I bought leaked one bit and I have used them over and over. Moreover, while the product states that the bottles are not dishwasher safe, they actually are so long as you do not run the heat dry cycle. The product description states that the bottles are temperature resistant (-40 to 60℃) where 60℃ is 140F. A typical residential dishwasher cycle runs between 120°F and 150°F, with the main wash cycle usually at 130°F-140°F. I have run mine in the dishwasher numerous times without a single bit of issue. This is true especially if you use the top rack. The bottles are actually easy to use and drinking from them is very easy, as well, as the opening is of a nice size.

I absolutely love these 12 oz plastic juice bottles! They’re the perfect size for my fresh juices and protein shakes. The tamper-proof black lids give a professional touch and seal tightly, so I never have to worry about leaks. I also appreciate that it comes with a brush and funnel—it makes cleaning and filling super easy. The bonus labels are adorable and make everything look neat and personalized. Great quality and super sturdy—I’ll definitely be buying more!

Works great for fruit juice and protein drinks.

Great little bottles. I use them for juice shots and they're the perfect size. The bottles are sealed easily. Cleaning is simple in warm soapy water. I have not tried to put them in the dishwasher.

These bottles are a great size for juice, smoothies, and even water. Designed well. They seal well, don’t leak, and are easy to fill and carry. The only downside is they aren’t truly dishwasher safe. I put a few on the top rack, and they melted/warped. As long as you hand-wash them, they work perfectly and feel very sturdy. Just keep in mind they won’t hold up in the dishwasher.

I love that I am able to put drinks in for my toddlers lunch and not have it spill out! I think its the perfect size for them too! I am so glad I found this because I really wanted something reusable but unfortunately everything I looked or used, just leaked. Just make sure it is tight!

I love these bottles, they do not leak. They're durable and resusable

Great purchase. I used them for juices and smoothies, they are practical when I’m running late I just grab and go. Better to restock them every week with any juice of you liking. Very durable and easy to wash.
