We had these rolls of removable jar labels specially made to peel off jars and bottles with no sticky mess. They are easy to remove when you've finished the jar.
Our jar labels come in rolls of 60, and we designed them to fit on small jars but also to have enough room for the name and date of your preserves.
We end up using ours on containers in the fridge and freezer too.
Each label is 60mm wide by 30mm high (2.36 x 1.18 inches) A great gift for any home preserver.
