Review on 🍷 Name It Marker: Metallic Wine Glass Pens, Food Grade Ink in Fun Colors! Personalize Your Drinks Like Wine Charms - Set of 8 by Cheryl Fisher

I use them to label plastic and glass food containers in fridges and freezers. I think freezer tape is annoying for a number of reasons, so after googling for the best solution I read that some people use wine glass markers like this. in the freezer. It doesn't always come out clean in the dishwasher (this can vary between plastic and glass) so I just wash with soap and water to remove the marker and then pop it in the dishwasher. Pretty cheap solution! I recommend this for labeling food containers instead of labels or tape.
