Jack is a 2-in-1 representation FTM stroker & packer made from 100% soft silicone. The stroker cavity is ribbed and will create fabulous suction for anatomy at least 1/2″ in diameter. Jack can stretch to accommodate larger anatomy. 

Jack may work with smaller anatomy but will not create any suction during use.
