I tried a couple different brands for labeling pre-prepared delivered meals for seniors. Some have poor vision and it was important to find one that sticks to both plastic and aluminum even in their freezer and one where my sharpie writing doesn't smudge. That's so they can clearly read what I wrote on the label like a "use by" date or other important info. This is the only one that has met my expectations. Finding one that stays on aluminum in the freezer or when damp was especially tough to find. I use only these and recommend them.
