Tantus's version of the multi-bloop anal plug comes in two sizes. The Large Ripple works for serious butt stimulation fans. The neck at the base on both sizes is on the long side, so it reassuringly stays in place. Measuring 7-1/4 inches long, 1-3/8 inches in diameter at the widest bloop and 7/8 inch diameter at the smallest bloop, the Large Ripple is made from silicone and is available in either Black or Purple.
