1st time purchasing glass food containers and these have been worth it.
Easy to clean, quite sturdy. 
Saw that it was oven safe and made myself a shepherds pie for lunch.
Worked out great!

Great price, great containers

I bought these storage containers around two years ago. I was looking for safe, clean, nontoxic containers for storage and occasional cooking. 

They are made with a high quality borosilicate glass, which is clear. Meaning they are lead, cadmium and heavy metals free. Borosilicate glass will break easier than some of dropped or hit against something. So you need to figure out if you're looking for durability or nontoxic when purchasing for sure. Non of mine have broke. I am careful with them though and wouldn't bring them out hiking or somewhere they could be banged around. 

The lids are BPA free which is fantastic. And are easy to snap into place and hold well once snapped on. 

If you are worried about durability or glass breaking, look for a tempered glass cookware option instead which is still way healthier than plastic. If you want a clean nontoxic option. These are fantastic.

Health conscious storage containers

Love this set! Great for the price. BPA free. Easy to clean. Some were complaining about the lids, but I found these very easy to snap on and off.

Great set!

They are difficult to close but when you get them closed they are sealed and will not leak.  I suggest closing the two opposite sides at the same time.  It gives you a better seal.

Excellent Set of Glass Containers

Glass tubberware

Product plastic fragile enough to break in transit. Product arrived broken. Overall pretty good product but for it to break in transit says a lot! Nice thick glass containers.

Product looks good but with cheap plastic.

The glass were nice and heavy, they do not leak and the lid vents were a good design choice but  One glass was chipped and the lid was broken which was a bummer.

The quality was ok but some glass came chipped.

product is good but i didn't check when i pick the pack and i got one less container , it include 6 container but i only find 5 whrn i reach home

having ok ok experience

Three came with the snaps broken. Still trying to find time to return. Online purchase because of kids and limited time. It's a purchase that was more inconvenient than convenient. Snaps are clearly cheaply made if they came broken, likely will not repurchase, instead I I think I will ask for money back. The containers were the perfect size I wanted so I am struggling with what I want to do..

Broken product received

One of my tupperwares came broken, customer service was horrible.
