These frozen labels adhere firmly to really lean containers of all kinds all over, but can be also without leaving adhesive residue, removed again. The adhesive is suitable even for direct contact with dry, non-fatty foodstuffs. Attached to the package is a step-by-step instructions for printing the labels in words and pictures, everything you need you can download for free. It looks very easy. I have not tried it, for my household I label the labels using the pen. But on the cold-resistant paper, other pins are possible. I am very glad to be able to use these labels, finally are the days of detaching itself in the freezer over. The dimensions of 38.1 x 21.2 mm are perfectly adequate for the labeling, the package quantity of 1625 pieces will be enough for me for a very long time. As usual, Avery, this is again a useful product.
