Discreet 2-Color Marker-Disguised Cart Battery That Stores 4g
Smyle Labs Penjamin Permanent Marker is a marker-disguised 510-thread vape battery engineered to look exactly like a everyday permanent marker while functioning as a cart battery with quick preheat and variable voltage. What sets this model apart is storage: the hollow marker body holds carts up to 4g and larger fully inside, so your cart travels concealed within the device rather than threaded on the outside. Available in two colorways, Black and Silver, it pairs that hidden-storage trick with genuine dual functionality. The device writes like a real permanent marker for everyday use and houses the 510-thread cart battery hardware inside the casing, complete with two marker tips in the box so it actually works as a marker. Variable voltage settings let you dial vapor density based on cart oil viscosity.
Penjamin Marker targets discreet daily-carry users who want a 510 cart battery indistinguishable from standard desk supplies, ideal for offices, classrooms, studios, and other settings where conventional vape devices would draw attention. The marker-shape concept differs from Smyle Labs' Penjamin Pen sister product in one key way: the marker's wider body swallows larger 4g carts whole, where the slimmer pen suits standard carts. That makes the Marker the right pick for anyone running bigger cartridges who still wants total concealment. Pair your Penjamin Marker with cartridges from our THC carts collection for compatible 510-thread oil options.
Variable voltage cycling lets you adjust vapor output based on concentrate viscosity, with lower voltage for thinner distillate carts that vaporize easily and higher voltage for thicker live resin or rosin carts that need more heat. The quick preheat function warms the cart oil before activation, eliminating the harsh first-hit experience common with cold 510 batteries on thicker concentrates. A discreet fire button sits hidden under the marker clip, so operation stays concealed, and USB-C charging keeps the device topped up with modern, fast, reversible connection. Browse our broader disposables collection as an alternative for users who prefer pre-filled vape options over refillable cart batteries.

Operating Instructions
Press the fire button five times rapidly to turn the Penjamin Marker on or off, the standard vape safety protocol that prevents accidental firing in pockets and bags. Once powered on, double-click the button to activate the quick preheat function for thicker concentrate carts that benefit from warm-up before drawing. Press the button three times rapidly to cycle through the variable voltage settings, matching output to cart viscosity. Thread a standard 510-thread cartridge into the cart adapter, seat it inside the marker body, and replace the extra-tall cap. Press and hold the hidden fire button under the clip while drawing through the mouthpiece. Recharge via the USB-C port when the battery indicator dims.
Marker-Disguised 510 Cart Battery for Discreet Daily Carry
Smyle Labs Penjamin Marker serves three distinct buyers within the discreet cart battery category. Big-cart users who run 4g and larger cartridges get a device that hides the whole cart inside the body, not just powers it. Office workers, students, and studio creatives get a 510 battery that disappears into everyday desk supplies where conventional vape pens would stand out. And daily-carry users who want a working permanent marker plus a concealed battery get true dual functionality with two marker tips in the box. The two-color choice, Black and Silver, keeps the disguise clean and professional. Penjamin Marker pairs naturally with the slimmer Penjamin Pen sister product for users who want a disguise option for both standard and oversized carts.
