1- Boomerang…  Allow pages to lie flat—prevents bunching. Makes it easier to turn pages, especially in large capacity or frequently used binders. Holes fit any style three-ring binders. Their boomerang shape gives the maximum page-turning power at a lower price.

2- Curved… An economic tool with provides lifting capabilities and sheets protection at the most inexpensive cost. These sheet lifters are subject to cracking in larger capacity binders with prolonged use. They do however give reasonably good service with moderate usage. In use, the outside curve should point toward the sheets. One curved sheet lifter is needed on each side of the sheets. They are sold in pairs.

4- Flat Poly… The poly sheet lifter give years of trouble-free service. The 3" works effective in 1" to 3" capacity binders. The 5" lifter particularly useful on "D" Ring binders. "D" Ring binders should only use one sheet lifter thus the reason they are sold singularly. A "D"  Ring or Slant "D" Ring is mounted to the back cover. If a second sheet lifter were to be used it would always remain on the cover and never move. This would render it useless.
