Progressive Prokeeper + Deli Storage Set: Air-Tight Silicone Sealed Containers w Grooved Bottom, Dry Erase Lid, BPA-Free, Stackable, Keeps Meats & Cheeses Fresh Longer, 3-Piece Set (1.65L, .69L, 1.6L)

Excellent Quality. Keeps contents very fresh..

Soy fanática de esta marca, no había comprado antes estos, sin embargo, después de varias semanas aún no encuentro la forma de abrirlos fácilmente, cierran tan bien que para abrirlos es toda una odisea

Got a set of different ProKeepers for Christmas and I loved them so much that I am adding to my collection. ProKeepers are well made and the sealing ability keeps food fresher longer. I absolutely love that they have different sizes and shapes for different foods!! I will definitely keep buying them (if need be 😉)

These work really well to keep deli meat and cheese fresh. They lock pretty tightly, which can be difficult to open for older adults or children, but I prefer that because it really locks out the air. They stack nicely in the fridge as well.

I was looking for something the right size to stick English muffin packs in. This was great. It's a little hard to open, but that also shows it is air tight. Of course, it can be used for anything that fits in it.
