300pcs Removable Freezer Labels, Yoget 1 x 3 Inch Food Labels, Refrigerator Freezer Tape Label Easy Clean Leaves No Residue, 2 Color Label Stickers Roll

I love my deli containers. These ones are great. I use them every day for leftovers. They're water tight and the lids are easy to take off. I freeze things in them all the time(soups, beans, etc). The only thing that's bad(and this won't be a problem with what you want to freeze) is that if you're freezing a liquid(water, broth, etc.) the lids are so good that the expanding pressure will bow the bottoms instead of popping the lids off. This makes them harder to stack. But they go back to normal with one round in the dishwasher. When I freeze my homemade bone broth I freeze them with the lids off and break up the ice on the surface every 2 hours while it's freezing. Consider getting these labels as well to write the name of the contents and the date. I use these for frozen stuff and they work perfectly. They're super easy to take off, don't come off by themselves at all, water doesn't mess them up, and they leave zero residue.
