The One Hander Kit
The One Hander made by Handr Innovations :
Theonehander™ is an affordable battery-operated device that uses vibrations to evenly fill and compact ground cannabis into 1 1/4 pre-rolled cones. Sometimes, we all need a hand and theonehander™ is a great way to fill your pre-rolled cones!
