We suggest that you write on it with a marker. But if you use chalk, when you accidentally write the wrong words, you can use a wet paper towel to gently wipe off the traces, and then write again after the water dries up. Remember to wipe it gently! Otherwise, the cardboard may be damaged! The beautiful, high quality printed artwork will catch the attention of your loved ones. Our photo props are sturdy but not heavy and meant to be reused. Easy to use: 1.Tear off the dot glue. 2.Stick the dot glue on the back of the card. 3.Finally stick the stick to the card.
