All metal hand weaving loom, 7" square. I had one just like it in the 1960's, and made many pot holders for my Mom and Grandma - I think I earned a Girl Scout badge for my efforts.
This loom looks as if has never been used. The hook is included. The loom is in the original box, and the instructions are on the back. The box is just a bit crushed from storage.
I checked, and Jersey Loops are still available!
