Lots of compliments on these . They don't look or feel cheap . Be very careful with the glass cylinders, they are pretty thin . I put a tiny crack in mine while filling it with some Aqurium gravel ( fixed it with a dab a silicone ) . I put some Bamboo stalks in them for the bathroom . Like many hanging products they don't come with nails or screws .

THEY ARE THINNER THAN I USUALLY BUY.  THESE ARE SO THIN THEY ARE ALL A LITTLE BENT.  BUT WILL BE FINE FOR MY USES.

They worked for what my roommate and I needed them for (Halloween)! They are really thin and I wouldn't recommend being to hard on them.

I was expecting these to be a little thicker, not sure why...but they work fine. I use the round ones for Bento style boxes for my toddler. The rectangular ones are kind of pointless because I don't have a pan that can support them, and I feel like pouring batter into them may make them collapse, but I can't say for certain because I haven't tried it yet. Also one of the rectangular ones arrived with a rip in the side, prob because they're so thin, but I didn't bother complaining about it.

Update: I found use for the rectangle ones for homemade candy bars or mini granola bars for the kids.

They are thinner that what I usually buy but just as strong.  I used them on a privacy screen and have had no issues with them breaking.

They are thin, but they work like they are supposed to, I would probably pay the price for them again, they are fairly cheaply made

They are very thin.  If you pinch them in the machine at all the tabs break off.  I would suggest that you take it out of your machine when you do not need it.  I have a feeling i will end up taping or even gluing it on.

It does what its supposed to beyond that.

I used these for a table decoration/centerpiece. they are fragile and crack/break with too much pressure, but that's expected given they are thin glass

Ok but a little thin for my liking I would like to see them made a little heavier so that when stuffing them full you wouldn't have to be so careful. That said they didn't tear and they worked out but they just felt as if they were about to.

Nice glasses but very thin I think they'd break easily. Beer tasts the same as it did in my cheap pint glasses.

Bags are thin...we have to be careful with them and not fill too full because they break.

they were a little smaller than what i expected, but if you are trying to lose weight or eat healthy they are good food portions, and the plastic is too thin. since you are heating, washing, and cooling it up. It will crack. I'm going to throw these away after all of them crack.

Extremely pretty but they are quite thin. I'm not sure how well they'll hold up after a few washes, but as we are only using these for our guest powder  room that's not much of an issue. The photo depicts the colours very accurately.
