ToysHeart and M's Japan collaborated to bring you a high stimulation design sleeve called Fuwatoro Dosnade. Using ToysHeart's signature “Foam Structure” design which incorporates tiny bubbles throughout the structure of the material. This material design allows the sleeve to be lighter, stretchier, and softer while keeping the durability property of the original material. As mentioned earlier, the inside tunnel is designed to be highly stimulating. This is done by the different stimulation zones. The semi-realistic entrance is simplified for a better durability and is angled to maximize a comfortable insertion. The narrow slit of the tunnel entrance also help with keeping the lube inside during use to minimize the need to stop and re-lube. Passed the entrance to find the first stimulation zone with three large stimulating nodes. The bottom two nodes are covered with tiny nubs while the top node is ribbed for high stimulation right from the start. Once you pass this zone, you are hit right away with three triangular ribbed node to change the stimulation. The middle section uses the upside down version of the beginning stimulation zone to further stimulate you. You are greeted towards the end of your stroke with two nub lined vacuum chamber for head massaging and to increase the suction of the hole. Simply squeeze the air out of the end as you enter to maximize suction. If all these weren't enough, the stinger is added at the end of the tunnel for your stimulation. Fuwatoro Dosnade is another great sleeve from ToysHeart and perfect for those who really like to kick their stimulation up.
