Question: Are they BPA free?
Document: These storage pieces are so easy to clean. The colors are very nice. The different sizes really come in handy. I love that there is no BPA. Great gift!
Great variety of sizes and shapes. Very useful and versatile. I plan to order an additional set so I can throw out all my plastic containers. No more BPA!
I have no problem with the Pyrex containers themselves, nor their lids. None at all. They are exactly what I would expect. But the packaging they came in...I am not happy about at all. The product description says "Ships in Certified Frustration-Free Packaging." Does that mean that they don't come in a Pyrex branded box, so that I could, you know, give these items as a gift, as I intended?
one of piece I put down to the stark beton  but didnot broken. First class therefore my vife very like them
it is worth use it (very useful). Love the colors and the sizes. I am planning to order more of those sizes.
i was expecting something bigger , but they are very good . . . . . . . . .
Well once they finally got here they were exactly what I'd wanted. But it's a good thing I was not in rush to get them because it took almost three week to arrive! !
This product is the best one, because it is very durable and in best price.I love it and I give 5 stars
This product is excellent!It came as promised and Pyrex brand always performs well. The glass is thick and sturdy to hold up to temperature changes (Oven/Freezer. I especially like the lids since they are tight fitting and reduces spills.
This is a very nice set for storing leftovers and is a great alternative to plastic. Would recommend to a friend.
Answer: Yes, "BPA Free" is printed on the lids.
