Great for adding volume to the roots/crown
The Cloud Nine system is excellent in that it's modular so you can choose how many of each size roller you want (as opposed to most sets where you generally don't get enough of the sizes you really want). The velcro is perfect for those with fine, silky hair who may have trouble with rolling onto hot smooth ceramic rollers.
These 50mm rollers get you subtle waves with a similar finish to a salon-style blow wave with a large barrel round brush. They're perfect for the top section to add big volume to the roots and crown.
Definitely recommended to expand your Ultimate Set or build your own set.
