You can split our stickers into PVC stickers, metal stickers and water transfer stickers. You can use PVC stickers directly. You bend the sticker sheet slightly and pick up the sticker with tweezers. For water transfer stickers, you have to remove it from the paper first.
You peel off the transparent film, cut out your sticker design and put it in lukewarm water. As soon as the sticker design comes off the paper, place it on a piece of kitchen roll to dry and use it afterwards. Metal stickers are made of zinc or copper and can be transferred to a hardened surface using the carrier film that comes with them.
