If you have the most unfortunate honour of having a tiny little dicklet hanging between your legs then this Holy Trainer v3 nub is exactly what you're looking for. No Master or Mistress wants to see that pathetic micro penis exposed, so get one of these chastity cages locked onto your poor excuse for a cock and willingly hand them the key.

Discretion is likely to be a significant consideration for you if you have a tiny penis as this device will likely add a little size to what you had before. Thankfully the internal lock still makes it secure and discreet, so you still don't need to worry. The lock comes with 2 keys, so you have a spare one in case of emergencies. If you have a long distance keyholder you can send one to them and freeze the spare key in ice. Send them regular pictures of the frozen key and they'll be encouraged that your teeny cock is still securely locked up.

This chastity device includes 4 ring sizes (36mm, 40mm, 45mm and 50mm) so that you can experiment to see which ring size fits you best. If you already own a V2 cage and ring set unfortunately they aren't compatible with this V3 version cage.

The Holy Trainer nub is completely waterproof and can be worn comfortably in the shower. Despite this, we still recommend that you remove the cage at least one a week to thoroughly clean yourself. If your keyholder does decide to unlock the cage and play with you (though with a cock that size I'd be surprised if they ever let you out) it's best to been clean. The tip of the cage has a urination hole, so you don't need to remove it at any point to pee.

We also have the Holy Trainer v3 available in maxi, standard, small and nano sizes if you don't have a pin dick and need something bigger. These sizes are available in clear, black and pink.

Wow! Just wow. After a week in a cb6000s which was clearly to big for me, my partner decided because of my shortcomings that she would order the Nub, I was concerned that I may be to large. How wrong can a man be! By far the most comfortable device I've worn with no chance of escape or sensation. When I look down now my ego has all but disappeared along with my cock.

Nub is the best yet

This is the best fitting and easiest chastity device that I have ever encountered. My tiny pindick has a little wriggle room, so perhaps another 5mm smaller would be perfect as I would like to feel the restriction on a permanent basis. However I am very happy with it, and so is my Mistress, which is even more important!

Excellent forced-feminisation device

I thought I'd need a cold shower before this went on, but it just slid on straight away. Very simple design - and quick to fit. Cage is less than 1 inch in length and basically makes it look and feel like your penis is gone. You can't masturbate as there is nothing there. It doesn't punish you for becoming erect - it just completely deletes your penis. The rings are shaped in different ways but they all appear to be escape proof. Internal lock is very discreet - make sure you don't lose or break the keys as I don't think there would be any way of removing the device without them. And be ready for massive and prolonged humiliation when your Mistress or Master finds out you are less than 1 inch in length. Would be nice to see a black and white version (perhaps with lace and ribbon accessories) to match a sissy maid outfit.

Finally found the one!!

Great shipping, great price, great size.... I finally found one that fits me correctly. I guess I was in denial ordering lager cage sizes. Absolutely perfect!!
