Model E STP — Compact Stand-to-Pee Packer by Number One Laboratory

The smallest STP in the collection — handmade for shorter folks, younger users, and anyone who needs a more compact fit.

The Model E STP is the most compact stand-to-pee device we carry — a 3-inch shaft designed specifically for people with smaller frames, shorter stature, or anyone for whom standard STP sizing has always felt too big. Made by Number One Laboratory from 100% body-safe platinum silicone with a soft powder finish — the matte outer texture is specifically designed to reduce chafing and eliminate that tacky silicone feel against skin. Every unit is completely handmade and individually quality-checked.

If you're looking for a mini packer rather than an STP and want more skin tone options, check out the Lil Buddy 3" Packer.

💪 Bulge Rating: 2 / 5

A compact, subtle presence — proportionate for smaller frames and shorter stature. Use the TGS Bulge Rating Guide to compare every STP and packer in the lineup.

🧼 Care & Cleaning

Platinum silicone is non-porous and easy to fully sterilize. Clean using any of the following:

• Hot water and soap — standard after-use clean
• TGS Packer & Toy Cleaner — fast, gentle, conditions the silicone surface
• Boil for 3–5 minutes — full sterilization
• Top rack dishwasher — no detergent required

Air-dry completely before storing. For long-term storage, dust lightly with Packer Renewing Powder to maintain the soft surface finish. Store in a cool, dry place out of direct sunlight.

Water-based lube only. Do not use silicone-based lubricants — they degrade platinum silicone over time.

🚿 First-Time Use Tips

Every STP device handles differently — even if you've used others before, give yourself a few sessions at home to find your positioning with the Model E. Work through these stages:

1. Shower, water off — practice the seal with no clothing so you can clearly identify any leaks
2. Toilet, no clothing — build muscle memory for cup placement
3. Underwear on — the Slingshot Harness or Cake Bandit STP underwear holds the Model E in the right position automatically
4. Fully dressed — once consistently clean at home fully clothed, you're ready for public use

❓ FAQ

Who is the Model E designed for?
Anyone who needs a smaller STP — shorter folks, smaller frames, younger users, or anyone for whom standard STP sizing has always felt oversized. At 3 inches, it's the most compact device in our lineup.

Is this good for beginners?
Yes — the compact size and powder finish make it comfortable to wear and learn on. If you're completely new to STPs, also read our Complete STP Guide before your first use.

What's the difference between this and the Lil Buddy?
The Lil Buddy 3" Packer is a soft packer only — it creates a bulge but doesn't function as an STP. The Model E is a fully functional stand-to-pee device. If you want STP function in the smallest possible size, this is the one.
