Guam Exclusive Wooden Surfboard Bookmark or Keychain This is a wooden surfboard-shaped bookmark featuring hibiscus and sea turtle designs exclusive to Guam. You can also turn it into a keychain by changing the string to a ball chain (see image 2). I have one hanging from my car's rearview mirror. The string is a leather cord with a wooden ball. The chain length is 12cm. The chain can be cut to adjust the length. Also, as a bonus, I have prepared one 12cm chain, so you can make it up to 24cm long.
