I Purchased this glass set because when I make red sauce it doesn't stain the bowl and you store food in the freezer so they cost more but you can do more. You do have to be careful because they are glass If you have a baby you store baby food and breast milk or store bought milk.

This 28-piece Pyrex glass bowl set is very cost effective. Good Job Sams. Our set's glass is unmarred, slightly thicker than some purchased individually over the years (interior diameter varies), and is made in USA. Pyrex glass pre-1998 was borosilicate and clear. The bluish color since then is due to the switch to soda-lime (like Ball™) - slightly less sudden-temp-change tolerant, but, honestly you should never be stressing glass anyway. The lids differ by the omission of a recycling #4 symbol - semi-meaningless but vintage Pyrex doesn't have it either. NO FLEXIBLE PLASTIC / RUBBER SHOULD ever BE HEATED - including these lids, which are for storage and transportation only. To microwave or oven-bake food, buy a few Pyrex glass covers just for that - available used & cheap by the thousands on auction sites. Measure the inside to get the right cover.

Good quality, best purchase of tuberware

Much better than plastic and easers to clean.

I love these glass storage containers. The various sizes are terrific!

One of the bowls had glass chips in the bottom and a rough edge inside.

expected Pyrex to be the best but Developed Small noticeable crack when I microwaved it just once.

I wish they were stackable love the glass and the food safety

Great value, great product. Need not say more.

Love these lids fit great sizes and microwave safe
