Good things come in small packages. So do you. So we made this.

Let's be honest. Not every situation calls for a maximum security facility. Sometimes… a cozy little studio apartment is more than enough.

NullForm is the mini cage that fits like it was made for you. Suspiciously well, actually.

Light as a secret. Snug as a consequence. And stylish enough that even your shame looks good.

Slip it on. Hand over the metaphorical keys. And enjoy the freedom of having absolutely no decisions to make down there.

✨ What Makes It Different

• Mini format – perfectly sized for those who were already working with a head start on humility
• Geometric ventilation cut-outs – because even small things deserve fresh air
• Integrated base ring – one seamless piece, no fumbling, no excuses
• Featherlight silicone – you'll barely feel it. Which, honestly, tracks.
• Matte black finish – making the smallest situations look incredibly dramatic since day one

📏 Size

Compact. Intentionally so. You're welcome.

🧠 The Experience

It weighs almost nothing. It means everything.

One moment you're a free man. The next you're standing in the kitchen making someone else's coffee, wondering how your life got so perfectly arranged.

NullForm doesn't judge. It just… fits.

Perfectly. Naturally. Like it always knew.

SIZE CALCULATOR

Measure manually for the base ring

Measure the circumference around your cock from behind the balls. You can use a fabric tape measure (the kind dressmakers use) to get the measurement, or, if you don’t have one, you can use a piece of string and a ruler. Wrap the tape measure or string around your cock, going behind the balls. The tape should be snug but not tight.

Now you have your circumference you need to divide it by 3.14 to get the diameter. We’ve done some sample calculations below to show you how it works:

In imperial:7 inches ÷ 3.14 = 2.25 inches diameter
6.25 inches ÷ 3.14 = 2 inches diameter
5.5 inches ÷ 3.14 = 1.75 inches diameter
4.7 inches ÷ 3.14 = 1.5 inches diameter
