This type of stamp is ideal for marking code number and ID information on SHAB test specimens (and many others) while in the plastic form. Set up the run or recipe number on the left and the specimen number on the right. You can find these stamps on Amazon by searching "12 digit rolling alphabet symbol number stamp".
