The EXE Kurea Hasumi + combines realistic textures with an intricate design to make a unique sensation. The inside of the sleeve can be described as a maze or gauntlet of stimulation. The first half of the sleeve has a varying width of alternating flaps to create more stimulation. These folds from the maze like structure also helps retain lotion during use in addition to providing stimulation. The end is a tight but mellowing texture to let you "wait" before the next stimulating stroke. This hole is also a dual-layer product which allows for a more stimulating material on the inside while having a soft material for gripping on the outside.
