Simple and quality

A simple grinder made out of quality machined and anodized aluminum at a good price . The grinder is a bit larger than I expected, the teeth design cuts easy and evenly. Good finger grip cut outs .I’m not sure how fine it grinds compared to others but its been nice for pipe use. The fall through holes are large enough that your seeds will safely fall into the lower part without damaging the seeds which is nice if you like to save seeds to re plant in the future.

Over all it’s simple, easy to use, cheap , made out of quality materials. I’d like to see GRAV make this same design but in food grade stainless steel

Came with a small little carry bag that I actually put my grav round bubbler in. and a small stainless steel scrapper

Amazing Grinder

Best grinder I’ve ever had! Super fast grinding, I love it. Super sleek too

Great grinder

So happy I bought this grinder only thing is it doesn’t have a Keefe screen but grinds flower good


Ordering from Canna box was a great decision! I LOVE my cozy cabin piece and it got here faster than any of my other orders I’ve placed.
