MECHANICAL PENCIL LEAD HOLDER?  Could be a salesman's sample as well....Im not really sure.

The bubble log on the top.  The side is marked #797R Black.

Made in the USA but I am not familiar with the hallmark.  Right from an estate sale.

CONDITION:  Nice condition.  The bubble logo is really nice.  Open as it should.

I HAVE MANY VINTAGE PENS FOR SALE INCLUDING MORE BUBBLE PENS.  PLEASE SEE MY OTHER LISTINGS AS I WILL DISCOUNT AND COMBINE SHIPPING IF YOU BUY MORE THAN ONE AT A TIME.
