There are lots of office supplies that are useful outside the office.
A local grocery store sells these for 86¢ per pack—Dollar Tree also sells them. With 350 to 450 dots per pack, they last a very long time.
These labels are handy in the kitchen.
Write the date on the label with a sharpie (fine point) or ink pen or pencil. Then stick the label on your plastic baggie, for example, once the food item is ready for the pantry or freezer.
I stash labels and pens/sharpies in a cute little basket on a wall shelf. Everything is easily accessible without cluttering up the kitchen.
Freezer tape is the conventional kitchen labeling method. But in a pinch, it’s nice to have alternatives.
