PenSimple is the modern answer to your old crusty grinder.

The sleek design of the PenSimple merely hints at the functionality it provides to your smoke sessions. Insert your nug into the top, give a couple twists to grind, then just press the button to dispense your favorite flower. There’s no mess, no sticky fingers, and it’s an awesome way to store your bud, always ready for a quick bowl or smoke circle.  Pack your dish full of herbs in seconds. The push button dispensing allows one-handed precision dispensing for careful herb placement.

While I did find PenSimple to be an impressive tool, it is a bit spendy. I opened the box thinking it was an auto-grinder but was somewhat dismayed to learn that it is indeed manual. And on top of that, the magnetic end cap is weaker than expected, so a moderate shake to release some stuck herbs sent the cap across the room. Even still, PenSimple offers some value in its clean dispensing and no doubt is a fantastic road trip tool.

PenSimple is very well-manufactured. Its black aluminum body is sleek and sturdy, and fucntions consistently, as long as you don’t over-stuff the grinder(same old story). Its charges via USB, and the charge seems to last through several uses. While not for everyone, PenSimple is a high-quality device that can save you some time, effort, and wasted weed. I’m sure everntually, that would make up for the hefty cost of PenSimple.




The PenSimple is made of 6061 aircraft-grade aluminum, making it lightweight and extremely durable. The rubber O-rings secure each piece together and make the device smell proof and spill proof. No longer do you have to worry about transferring herbs by hand, simply pick up the device, point, and shoot. This saves you time, it saves your hands and saves your herbs. 

PenSimple is revolutionary both in its design and function. Unlike other herb grinders on the market, the modular design allows for limitless possibilities and future accessories. The modularity also allows for extremely easy cleaning.


PenSimple is a revolutionary herb grinder and portable storage vault that makes your ground herbs accessible at the push of a button. Store up to 3 grams of your favorite ground herbs ready to dispense. Never experience sticky fingers or a spilled grinder again with the secure and efficient design of PenSimple.
