The Real Boy Kit is Perfect Fit's first dildo product that comes in a combo pack with the opaque white Fat Boy Thin (CS-03C). The sheath fits perfectly over the dong, hooking over the scrotum which creates a super tight vacuum seal making it one of the most realistic feeling dong products available on the market. You can also use the dong without the sheath which has a suction cup at the base of the dong which easily secures to many surfaces. You can also use the Fat Boy Thin without the dong for penetration or masturbation making it a 4 in 1 multi-use product. The Real Boy Kit dong is made of TPE (Thermoplastic elastomer) which is a remarkable new safe material that is 100% recyclable. The Fat Boy Thin is made of SilaSkin, which is a perfect mix of Silicone and TPR which gives it an unbelievable stretch factor. The Inner dimension of the Fat Boy thin is 6.5" and the Real Boy Dong is 7.5". This product is not compatible with latex products. The Fat Boy Kit is safe with most lubes. Wash thoroughly with mild soap and water. The Real Boy Kit comes with an opaque white Fat Boy Thin. This product is porous and not a substitute for a condom.
