Let me walk you through this. This is a hollowed-out book. The original book was from a library sale but has been replaced with a new cover entitled "A Planeswalker's Guide to Ravnica by Jace Beleren". Featuring art kindly provided by Wizards, it purports to be a travel guide to Ravnica written by Jace.
Inside however is ten signet rings, one for each of the guilds. 3D printed in stainless steel and finished by hand, they can adorn a finger and be used to press the guild symbol into wax, clay, and the like. Also included is a necklace for wearing the rings as pendants (if they are not your size) and a stick of wax.
This project was produced for the Desert Bus Craftalong to raise money for Child's Play. If it's something you think you'd like to bid on, keep an eye on www.desertbus.org around November when Desert Bus For Hope 6 begins.
