I came across this in an estate and it is in very good condition . It is approx 7 inches in length with the one end removable. It has the engraving “THANK YOU DAD”. No other markingA I could find. I did a Google search and they r referenced something like cigar tube only sterling silver. This is not magnetic as I can see. Your call. Selling in the as is condition . No dings or dents. Check the pictures for more details as they are considered as part of the description.
