OTTO Grinder

The OTTO Grinder by Banana Bros. is an automatic, rechargeable grinder that analyzes your flower before grinding it to perfection, and then releases it neatly into a pre-rolled cone. This quick and efficient tool makes preparing a joint effortless, especially when you’re preparing several at a time before a night out, or while entertaining a group of friends (and it’s nicely paired with the Audrey Louise Reynolds x Devambez Paris Watercolor Pre-Roll Cone). OTTO’s precision blades don’t compress or turn your flower to powder, but preserve the plant’s aromatic compounds for better potency and flavor.
Color: Black
