Glass Guardian (Royal Blue)-Eco-friendly glass bottle cover fits bottles 2.5"-3" diameter. Decrease plastic use and leaching chemicals by using glass with bottle protection!

After learning of the dangers of plastic bottles I decided to make the switch to glass. Unfortunately, unlike plastic, glass breaks. So I really like the Glass because it helps against breakage and gives you grip to cut down on potential drops. Great Product!

After breaking countless bottles of wine while hosting parties I figured I would try this. Simply it works. I still knock the occasional bottle over but now they don't break. An added feature is that due to the texture of the guardian it makes passing and pouring the wine so much easier because now I have something to grip and hold on to.

Works great!!! I've accidently dropped my glass bottle several times at the gym and haven't had it break or even crack. I recommend it for anyone who uses glass water bottles on a regular basis.

This product is great! After extensive research, and some trial & error, I settled on Tommee Tippee glass baby bottles for my new baby. Unfortunately, they don't offer any kind of sleeve to prevent breakage. I figured I could deal with that later. When the time came, and my son was about ready to start holding his own bottle, I decided to try this product. I kept my fingers crossed, hoping it would fit such a strangely shaped baby bottle. To my pleasant surprise, the Glass Guardian fit like it was made for the Tommee Tippee glass bottle.Now I can take my son out in his stroller, drinking out of a glass baby bottle, without worrying it's going to shatter when dropped. Funny enough, now I'm searching for glass sippy cups, and realized the Glass Guardian will make an excellent sleeve for any glass cup. Now I just wish the Glass Guardian would make a sippy lid too. Until then, I'll be using the Glass Guardian base with a Boon Snug silicone sippy lid.

Fits a 2 cup "regular-mouth" mason jar perfectly, and protects my smoothie on the way to work. When you wash the jar, some water will get into the bottom, and it won't come out unless you remove the sleeve. But trust their instructions to rub a little dish soap on the jar - that makes it _so much_ easier to put on.
