It works well on medium size favor containers, tin tie bags, liqueur bottles, small bottles etc. It is NOT MEANT for the main label of regular size wine bottles or beer bottles.
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.
