The Pen Deluxe is a solid stainless steel chastity cage that locks from the inside, so there's no padlock hanging off the front and nothing to catch on clothes. Three O-ring sizes come in the box, which is what most people need to find a fit that stays put without pinching.

Features

• Internal lock: turn the key in the brass keyhole to straighten the lock, seat it in the hinge, then turn again to close it. Flat profile, no dangling hardware.
• Three O-rings included: 1.5, 1.75, and 2 inch inside diameter, so you can size up or down without buying a second cage.
• Cage size: 2.25 inches long, 1.3 inches across. Built for a snug flaccid fit, not a roomy one.
• Open bar design for airflow and quick rinsing at the sink.
• Real weight: polished grey steel gives a constant, quiet reminder that molded plastic cages just don't.

Materials and care

Stainless steel body with a brass keyhole, grey finish. Wash with warm water and mild soap, rinse thoroughly, and dry it completely before the next wear. Steel is compatible with every lube type, water based or silicone. Stash the spare key somewhere you'll actually find it in a hurry.

The honest part

Steel is heavy, and that's the point, but it also means this one gets cold in winter and will absolutely set off a metal detector. The 2.25 inch cage runs short, so if you measure over about 2.5 inches soft, look at a longer cage instead. Ring sizing takes a couple of tries: too tight and you'll feel it within the hour, too loose and it slips off. Plan on removing it daily at first for cleaning and skin checks. This is a wearable device, not a medical one, so take it off if you have numbness, discoloration, or pain that doesn't settle.

FAQ

How do I pick the right O-ring?

Measure around the base of the shaft and testicles with a soft tape, then divide by 3.14 to get a diameter. Start with the middle 1.75 inch ring, and go up or down from there based on whether it pinches or shifts.

Can I sleep in it or wear it all day?

Plenty of people do after the first week of getting used to it, but start with a few daytime hours and work up. Nighttime erections are where most people find out their ring is too small.

How discreet is the shipping?

Plain box, no product names or store branding outside, and the billing descriptor doesn't say what you bought. Nothing on the label hints at the contents.
