A magnetic clip is provided having two magnetic components to create a low-cost, thin, soft magnetic vise-like mechanism. The magnetic components are disposed in individual stickers or a unitary sticker. The clip includes an adhesive layer to which a real banknote may be removably attached. The user can simply peel back the banknote to open the magnetic vise-like mechanism to insert or remove one or more banknotes. The user then folds the substrate back onto itself to close and secure the remaining banknote(s).
