Swell is designed for men who enjoy anal/prostate stimulation and who are experienced and prefer being filled/stretched. There's no reason a woman couldn't use this vaginally or anally, however. In my personal opinion, this is for those who have experienced with larger objects. It is girthier than a beginner toy, even without inflating it.

It can be used for solo or couples play. Bonus: it has a remote control for partner play. Lots of fun possibilities there.

The material is 100% silicone on the exterior and waterproof. It has a smooth matte finish. Use plenty of water-based lubes with silicone toys. It is rigid and expands with the pneumatic feature. Strictly for more advanced users. Tight holes may struggle with inserting this.

This toy is 4 3/4" long (4" insertable length). It is a girthy 1 3/4" diameter (5 1/2" circumference)

It weighs in at 4.5oz. The shape is designed to stimulate the prostate and is tapered for hands-free retention.

This toy has good vibrations and is for hands-free stimulation, though you will need to push buttons to change modes or to use the inflating feature. It has a variety of vibration patterns. The pneumatic function inflates and deflates in intervals and expands quite a bit. All the functions are controlled via remote control.

This toy is waterproof and can be washed with toy cleaner, 10% bleach solution or hot soap and water. Dry after washing and store in a pouch or box to prevent dust build-up silicone toys are famous for. It is rechargeable and should be stored in a cool/dry place.
