Now there's Thumb Thing to help the teacher with not enough hands. This unique patented book holder fits on the thumb like a ring and spreads the pages of the book open. Perfect for reading while holding the book in one hand! The "Small" size is just right for young students, and for many adults as well.
Size Matters! There are four sizes of Thumb Thing. Measure the width of your thumb just above the knuckle, and choose from these sizes so the Thumb Thing fits comfortably as shown in the picture:
- Small: 17mm (11/16") opening
- Medium: 19mm (3/4") opening
- Large: 21mm (13/16") opening
- X-Large: 23mm (29/32") opening
Assorted colors, we'll ship colors chosen at random.
