Penjamin Permanent Marker Cart Battery — Hide Your Cart in Plain Sight

To everyone around you, it’s a permanent marker. A boring, unremarkable office supply sitting in your bag, your desk drawer, or your shirt pocket. Nobody gives it a second glance — because why would they? It’s a marker.

Inside, it’s a fully functional variable voltage cart battery holding up to 4g carts. That’s the entire point of the Penjamin by Smyle Labs, and it executes the concept flawlessly. The disguise isn’t cosmetic — it’s a working permanent marker, complete with real marker tips, so it holds up to actual scrutiny. Pull the cap off in front of anyone and all they’ll see is a marker.

What’s Inside the Marker

• Fits carts 4g and larger
• Variable voltage for dialing in your preferred draw

Built for Everyday Carry

The Penjamin is sized and weighted like a real marker because it is one. Toss it in a pencil case, leave it on your desk, drop it in a bag — it disappears into plain sight wherever you put it. No specialty cases, no suspicious silhouettes, no explaining yourself. Just a marker that happens to have a cart in it.
