This weed crusher (grinder) has a tough metal body, made of aluminium, whilst the lid, upper and lower sections are made from acrylic. All neatly held together by a magnet. The middle aluminium section contains a fine pollen screen for capturing that otherwise lost precious pollen. With Pyramid Shredding Teeth this grinder is sure to make short work of any bud. There are different colours, a colour choice is not possible, but we will send you a -wild- colour mix, if you order more than one piece.
