Cadie Permanent Freezer Marker Set of 2 – Waterproof Fast-Drying Black Ink Pens with Chisel Tip for Food Labeling, Fridge & Freezer Storage, Kitchen & Lab Use & General Organization.

Writes well on plastic bags/containers, does not smear once dry (dries quick) and- bonus- it washes off with dish soap and water, so no more stacked labels on reused containers. If the tip gets wet while using, it will not write anymore, but if you cap it and let it sit awhile it will be perfect again. Will definitely buy again! Still working months later!

Very effective pen. Lasts quite awhile. Do NOT write directly on anything. None of the long-recommended home remedies for removing permanent ink will work. Writing fades but is not gone. That is a good thing unless you're careless and assume you can remove the writing...I do recommend them.

Fast drying and easy to use. Stays bold, doesn't fade

I absolutely loved these markers! The ink doesn't run—you can use them in the kitchen to label food for the freezer, and even if they get wet, the writing doesn't smudge or fade. These are markers of excellent quality.

3 months later and it still works. Has not dried up. I use it to write on my breast milk bags.

Happy with this product. Good strong marker

I'm on the fence about this one. I bake and freeze a lot and was using just a pen to write on the outside. Found that the ink smears so bought these to see if they would work better. They did. I would have given it more stars if the pens were thinner. It's not easy to write with being so thick. They are still better than what I was using and the paper sticks to the plastic and foil easily.

Perfect for freezer tape. Stays dark and visible.
