I failed my first attempt and didn’t want to wait for the shipping for the replacement pack of the mold powder, ended up finding a pound of it for $10 at Hobby lobby (Perfect mold- green and blue package) that worked great, the issue was staying hard, i cut the tube to size and cut both ends off, had my wife pour it over the top of it and to stay hard had her sit on my face and play with my balls (did not get the balls edition) after it dried, wiggled it off and taped the end of the tube on and waited the recommended 2 hours, i did buy the extra casting as i am above 9in and it was definitely needed. came out perfect, hope this helps someone.
