Kennicki Nice little bookmarks - I purchased these in person, so I was aware of what material they were. I used mine when I traveled to NYC and they’ve held up great! Very nice to look at and got the job done. Magnets are strong and the elephants are made of a thin card stock. They probably won’t last very long as the card stock is quite thin and the design of the elephant makes it easy to bend (trunk and feet) still, happy with purchase.
