I also make CUSTOM STAMPS AND MAKER MARKS - feel free to contact me for more info.
My stamps are made of Delrin - well known high density synthetic material resistant to pressing.
They won't break if used properly and with care, they are very durable and they have a very reasonable Price.
This is a Delrin embosing wheel that fits my Leather embosing machine LEM-1000 available soon at my etsy shop here :
