This cock and ball spreader/divider by Spartacus has many uses:
1st it can be used just to make the erection firmer.
2nd it can be used to tighten up the balls.
3rd it an be used in Cock & Ball Torture (CBT) play.

It can be used by all levels from beginners to advanced users. Warning: this item comes in various sizes. Start on the smaller side & work your way up if you dare. My boys normally ride high and tight. I chose the 2" and am extremely happy with the size.

It is easy to get into the Spartacus stretcher/divider. The 1/2 inch strap with the metal D-ring faces downward. Either I or my girlfriend will: Pull my testicles down with my left hand and wrap the leather around with my right hand, & then use both hands to snap the snaps. I then twist the stretcher so the lower divider strap will divide the balls. Then it is up & around for the cock ring strap.

Spartacus knows their leather. There aren't any sharp edges that could ruin the fun. There aren't any loose threads. This product will last a lifetime of snapping around my cock and balls without wearing out.
They make 4 sizes, and the sizing is the length of the leather that houses the balls. If you are a beginner go with a smaller length as you will still receive the benefits of the stretcher/divider. If you go too long you will injure yourself.
Any time you feel your balls get cold or turn purple take it off as blood isn't circulating enough. This is not intended for long term wear. It is also very difficult to wear with clothing as clothing will push up against your balls in an extremely uncomfortable way.

The cock ring has a 1/2” wide strap which has 3 snaps to snugly fit almost any size penis, as long as you are near the diameters of 1 1/2”, 1 3/4", or 2 1/2".

The ball stretcher comes in lengths ranging from 1” to 3” in 1/2” increments. Every length has 2 rows of snaps running down the left and right sides of the stretcher. This allows you to grip or grasp your balls. The outer snaps make a diameter approximately 1 3/4” and if you really like thing tight you can use the inside snaps to grasp your balls with a 1 1/4” diameter. There are 4 snaps for the ball divider, if desired, which will make the tight grasp of this divider even tighter. The strap is about 1/2" wide and has a D-ring attached if weight or rope is fancied.

The Spartacus separator/divider exceeded my expectations. The moment it is placed around my balls I get an extremely hard erection, harder & faster than the leading ED (erectile dysfunction) pill. I do not have any ED issues and can not make any claims if it will work for those with an ED issue, but we prefer this to any blue pill.

The packaging was a simple plain small plastic bag with a sticker on it. Nothing fancy & nothing wasteful.

This product, being a non toy, has found its way into the bedroom for couples play as well as solo time.
During couples play my girlfriend will put the stretcher on me when she wants me to be as hard as a rock, or when she wants to be the domme that night, as she can slap my balls and I will really feel it. She also has attached some weights to the divider D-ring to add to the stretching while standing. She has also attached a rope to the D-ring and to ankle cuffs so when I squirm or she slaps the rope tension occurs, which she enjoys.

During solo use I will masturbate with it on, or just put it on to feel how hard I get while wearing it.

Evey man should have 1 of these in their toy collection. It looks hot & feels wonderful, and can lead into kinky domme play if desired.
