420 science 4 piece grinder

Regular price £40.00 Sale

A 420 Science Grinder!

Unlike some other herb grinders, each layer is one solid piece of aerospace aluminum. The large chamber allows for up to 2.5 grams of herbs to be ground. This designer grinder uses diamond-cut teeth to crush your herbs into a nicely blended and fluffed texture, keeping your fingers clean and your bowls evenly distributed. Hands down the best grinder you'll find at this price.
