Cadie Freezer Black Permanent Markers Fast Drying, Waterproof Marker for Labeling, Chisel Tip Marker, Lab Marker, Food Labeling and Dating Pens for Easy Writing on Paper, Foil, Plastic and Glass

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.

Lasts for a long time but I’ve found it catches on the freezer bags I write on so I have to press lightly.

The pen works perfectly with the removable labels.

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