Our company is happy to present the first medical grinder, The KUBE Walnut Grinder. What makes our grinder a medical grinder, well a few things. The ergonomic design coupled with a two part design that will not adulter the THC content is a good start.

Kube grinder made from a black walnut shell with an anodized aluminium core. The Madera Kube features a sloped dish on the back side that is great for your freshly shredded cannabis and can also be used to recover the ashes of your session.
