When you wear something that works on multiple levels at once, the whole experience shifts. This is not just about staying harder longer, though that happens. It is about what you feel during, and what your partner feels too. The Double Dolphin puts two independent vibrating stimulators exactly where they matter, and the result is a noticeably fuller, more connected session from start to finish.Slipping it on takes seconds. Once it is in place, the two removable dolphin stimulators do their thing hands-free. One sits against you, one positions against her. Both vibrate independently, which means you are both getting something the entire time without either of you having to think about it. The ring itself is a flexible PVC enhancer, comfortable enough to wear without distraction, snug enough to do its job. The stimulators are ABS with silver plating, solid and smooth against skin. Batteries are already included, so you are not waiting on anything.Some toys you have to work to get value out of. This one just works. You put it on, you both feel it, and you wonder why you waited this long to add something like this to the rotation. It ships ready to go, and so are you.Product DetailsMaterial: PVC (enhancer), ABS with silver plating (stimulators)Power: Battery-powered (3 watch batteries per stimulator, 6 included total)What's Included: Double Dolphin enhancer, 2 removable stimulators, 6 watch batteries
