A hangtag includes a foldable flap and a rubber ring girdling around at least one pore of the foldable flap, the rubber ring having a connecting element shaped into column, a hanging portion and a mounting portion being individually deployed on the opposite ends of the connecting element, the hanging portion and the connecting element passing through the pore and the mounting portion which leads the mounting portion to tie a knot; in such a way that the user may easily turn around the hangtag and spread out the foldable flap for reading.
