OXO Kitchenware: 3-Piece OXO Pop Food Storage Container Set EXPIRED

That's technically correct. However, I have both and I don't see much of a difference to be honest...if that helps.

Their two lines are Goodgrips (better, sold at BB&B and most nicer stores) and Softworks (sold at Target, Marshalls, Costco, others). These look like the higher end ones, but without a box, it's hard to confirm. But Macy's sell goodgrips stuff, so these are probably goodgrips too

For utensils, the softworks stuff is noticeably less good. Cheaper materials, basically self-made knockoffs. For the POP containers, they're VERY similar. Sizes are ever so slightly different for whatever reason, and some have rounded square buttons instead of circle. Beyond that, they're almost indistinguishable.

****That all being said, they recently updated the design on these. The lids are thinner which allows them to fit a little more, but they make a MUCH worse seal than the old ones. When they're full, you cannot lift the new ones by the lids. The lids just pull off when you try. They make a good enough seal on the shelf, but you could easily pick it up wrong and have it drop and spill. The older ones were much better, both goodgrips and softworks.

For reference, the Costco set is 9-piece and was $47.99 on sale. I ended up buying two sets and have been happy with them.
