This was something cooked up internally to assist us in rolling h-holes/donuts. We use it to press our flower into an even patty on standard 1¼ papers, to assist in rolling around the concentrate 'worm'...
Designed for 1¼ papers.
This listing is for one press (two are pictured in the product photo for illustrative purposes).
This 3D Printed PLA plastic item is sold for novelty purposes.
