This is the world's easiest way to revoke limb privileges. Period! The Clinger is a set of "sticky" strips of soft fabric that help secure flailing limbs with next to zero effort. The pieces literally stick to themselves so you can wrap around the baby's legs, arms, etc and it will just stay where you stick it to itself! The pieces are just stretchy enough to hug the baby, but stiff enough to keep baby in place. These are meant to be used as an under-wrap or a way to secure the arms/legs for specific set ups such as mugshots, night-night, and more. Each set includes 6 pieces in total that can all connect to each other as desired. There are 3 different sizes, as shown. We recommend buying a second set if you shoot twins with any regularity....or if you just want a backup set! **The videos with the weights are for demonstration purposes only. Let's be serious, this was not an official scientific experiment.
