These holds are a blast on our 40 degree home wall. Super solid construction and definitely worth the price.
Varying levels of the amount of the ball that is exposed providing varying levels of incut. Awesome for steep walls as sometimes normal half dome slopers are very difficult. These allow you to get your hand behind it even on a 45°. This set I particular I love because they can also be used as pinches. They range in size from baseball to softball. The sloped edges make this awesome to to force certain moves and accuracy.
