I wonder why there are two sheets of cardboard inside. The carbon paper barely lasts for one impression, and even if you don't press hard and do it gently, the previous impression remains on the new one. It barely suffices for one attempt with no room for mistakes

It is a great product and it has a beautiful result. It is good to buy it when your baby is still small because it will be difficult to get a good imprint as they grow, as they will not sit still and of course their hand or foot will not fit. It is easy to use and with a little attention and patience, it produces very nice imprints either from the foot or the hand. Each package has a carbon copy and two cards. To get a good imprint, I advise you not to press too hard on the surface of the carbon copy. After all, you are dealing with such tiny little feet and hands. I would not recommend making an imprint of the foot and hand with the same carbon copy, as the first imprint leaves a design. Personally, I bought 2 packages and used one for the hand and the other for the foot. Finally, I barely managed to fit the foot and hand of a 5-month-old baby with normal height and weight indicators.
