Can you imagine driving other people's screaming, insane, crazy children around to and from school, five days a week, for an entire school year? We can't either. It sounds exactly like torture to us.... and that special person who has the ability to do this job DESERVES A GIFT. Make it a hand stamped school bus driver gift! Ready to go for the beginning, and end, of school year! Shank size: 1/2" Stamped impression height: 12mm While this stamp is rated for stainless steel, your best impression will be in soft metals.
