It can be difficult to decide between an open-handed, sloper, or even pinch grip when choosing a hold. But why choose in the first place when one hold lets you set any type of grip you want? eXpression’s shaper gambled and clearly won this time around with our Boulder Pure Eggs Mini Volumes series and the Pure Eggs Mini Volume 4 (PE) does not disappoint. Among the 5 mini volumes, this is the second flattest. If you want a flatter hold, check out the shape of our Mini Volume 5. The additional screw hole provides a more secure attachment and a wider variety of setting positions.
