These adhesive chalkboard tags are tick, durable, and can be reusable if the instructions are carefully followed. There are 48 in the pack so I didn't have the need to reuse any of them myself.
They come in a variety of shapes that aren't your standard rectangle and oval. I used chalk markers to write names on them to use as gift tags. You could also use them as storage labels, for crafts and all kinds of things!
