These can be found sometimes in containers. Old copper strips with nail holes in them, turn out to be strips which were nailed into cracks around doors, to prevent draught, I use them for Thoughtkeepers. A separate space for thoughts and texts. There is a Jewish tradition of hanging a small decorative container on a doorpost. A mezuzah contains texts from the Torah. The warmth of your faith keeps the cold from your house... with a good draught strip of course!
* Mezusha is the Hebrew word for doorway
