When was the last time you looked at something under a magnifying glass? We're betting that for most of you (us included), it's been awhile. Magnifying glasses use a curved, or convex, for you science types - piece of glass to distort an object, making it look bigger to the eye. Okay, enough physics. You won't need to use a magnifying glass to make your or your partner look bigger with Renegade's Medium Fantasy Extension. The crystal clear, naturally curvy nature of the soft jelly material will do the work for you, plus, the penis or strap-on in question will actually BE bigger. That's the magic of a really great extension sleeve, folks!
