Rollga Large Peanut - great addition to rollers
I've had Rollgas since they first came out (different firmness levels) - and love them! I received the Rollga Large Peanut for Christmas. It is amazing as the size & shape is able to activate areas in my back & shoulders more deeply than the original Rollga. They are a great combination! Highly recommend this combination
