The Clone-A-Willy Glow kit lets you make a silicone copy of a real penis at home, with a vibrator set inside, that glows in the dark when the lights go off. It is the same idea as the classic Clone-A-Willy kit, with glow powder added to the silicone.
It is a project, not a ready-made toy: you make a mold, pour the silicone and leave it overnight. The result is a one-of-a-kind vibrating dildo. PinkCherry lists the Clone-A-Willy Glow among its best sellers, and the Clone-A-Willy kits are some of the most searched-for products in adult toys.

HOW THE GLOW WORKS
The Clone-A-Willy Glow gets its light from zinc sulfide phosphorescence, Clone-A-Willy explains. The pigment soaks up light and slowly gives it back in the dark. Leave the finished copy under a lamp or in daylight before you turn off the lights, and recharge it with light whenever the glow fades.
FROM MOLD TO GLOWING COPY
- Read the printed instructions first; the thermometer is there because water temperature matters for the mold.
- Mix the molding powder, fill the tube and hold the erection in place for about 60 to 90 seconds while it sets.
- Mix the two silicone parts and stir in the glow powder as the instructions say.
- Pour the silicone into the mold and set the vibrator in place.
- Leave it to cure overnight, then cut away the tube and peel off the mold.
Over about 8 to 9 inches, Clone-A-Willy suggests the XL vibrator and extra silicone. A molding powder refill lets you have a second try with a new mold.

CLONE-A-WILLY GLOW QUESTIONS
How do you make the Clone-A-Willy Glow light up?
Leave the finished copy under a lamp or in daylight for a while, then turn the lights off. Clone-A-Willy explains that the glow comes from zinc sulfide phosphorescence: the pigment stores light and gives it back in the dark, so it needs topping up with light each time.
Why does the Clone-A-Willy Glow silicone look clear in the box?
That’s normal for this kit. Clone-A-Willy ships the glow version as two clear jars of silicone plus a separate bag of glow powder, which you stir in as the instructions say.
What do I need that isn’t in the box?
Scissors, a mixing bowl and utensils, and a disposable bowl or cup. Everything else, including the thermometer, is in the kit.
How long before a Clone-A-Willy Glow copy is ready?
Plan on a day. The mold sets in about 60 to 90 seconds, but the silicone needs to cure overnight before you remove it.
Will it fit a very long or thick penis?
The tube is 10.8 in long and 2.5 in wide. For about 8 to 9 inches or more, Clone-A-Willy suggests the XL vibrator and extra silicone.
