The Corkscrew can be worn on top of your Innerwear for an active all-day stretch. Simply slide it on and twist the last few coils to secure in place. This targets the suspensory ligaments of your penis to gain length faster. Innerwear sold separately.


The corkscrew is available in all 99 original Stealth sizes for a perfect fit.


Unlike other stretchers, the Corkscrew can be comfortably worn for 8+ hours.


Can be concealed under loose fitting clothing and worn during your daily activities.

  • Honestly I've tried so many methods to enhance what I've got for nearly 10 years, finally found a product that's doing the business for me.
  • I just made my second purchase, I must say it is an ingenius design and concept. Now I have an underwear bulge I can be proud of!
  • Stealth feels awesome, I just adjusted my package and it feels heavy and thick!... cash your check, the Stealth is well worth the money!
  • What I like best is that you can wear it to achieve an enhanced but naturally looking bulge. A great product to increase girth, length and soft size.

Measuring Instructions


To measure length: In the flaccid (soft) condition, clamp your penis head using your thumb and finger. Fully extend your penis to a comfortable stretch. Lightly press the ruler slightly (1/2" only) into the fat pad towards the pubic bone. Measure along your shaft without including your penis head.


To measure girth: Once again, fully extend your penis to a comfortable stretch. Use a measuring tape to measure the circumference of your shaft right behind the penis head. If you do not have a measuring tape, wrap a strip of paper behind your penis head. Mark the strip of paper and then measure the distance on a ruler.


After you’ve measured yourself and double-checked for accuracy, enter your length and girth into the drop-down menus. Our calculator will automatically choose the most suitable size for you. The size code will be shown in the display box for your reference. You may manually adjust it, if needed.

Very Nice

Rick Farao
Surprisingly satisfied

I was expecting another gimmick stretcher. Many of the types of stretching devices I have used from other brands and styles have all in some way have hurt to wear after awhile. I would take them off and had to allow my member to recover, sometimes up to a week. This cork screw may be heavy, bulky and not practical for wearing to work or in public. But I have to say that is one of the more comfortable devices I’ve worn. I wear it as much as possible. I feel this product will work well over a long period of time. The coil expands out quite a bit from its original shape. The combination of the weight of the coil and the fact that as you expand the coil it does not retract back easily. It will hold its shape if applied correctly. I recommend this device for those who want the gains and have the patience.

A little practice

After trying the corkscrew for a couple of days it gets easier to put the corkscrew on. I have found that you can relieve the weight of the corkscrew on the glans by tightening the corkscrew along the entire shaft. The corkscrew is quite heavy so this helps to distribute the load. Love this device, I could wear it all day.

Underwear and corkscrew

This is a great product. The inner wear is very comfortable, I could wear it all day. Love the weight of the corkscrew as it pulls down on me.

Happy customer
Corkscrew is the key

Hello, I love the corkscrew , it is heavy but feels amazing. This thing does it’s Job, it’s adjustable, and you can make it smaller if needed. You can make it tighter or more loose by twisting the corkscrew toward you or away from you. while wearing on the go. I recommend this awesome device.
