I thought mine didn’t come with a screwdriver but I most likely just threw it away accidentally. In the spirit of 4/20 they sent me a replacement for free! SO GRATEFUL!! I would have gladly paid the few bucks for the replacement. On a $20 product it’s cool that they even have a replacement screwdriver and screws at all to buy instead of just making you buy a whole separate coil guard. Thank you MiniNail!
