This shape was designed for quart canning jars and wine bottles, and also works well on wine boxes, large tin tie bags, large favor boxes, etc. It is slightly short as a wine label, so will work on bottles that are a little shorter than standard.
The illustration below is not at actual size, but it shows you how this item compares in size to a credit card.
If you are not sure this size will fit your container, draw the shape on a piece of
paper using a ruler to measure, cut it out and lay it on your container.
