This herb grinder is crafted with heavy-duty zinc alloy, 4 parts & 3 chambers, special drum shape.
The magnet on the top of this grinder is very strong, and the magnetized lid helps greatly reduce spillage. Unlike other weed grinders, the cover is easy to fall off during operation. This dry herb grinder with powerful magnets holds the lid firmly in place. This crusher is easily twisted and does not make annoying metallic noises
