These are really neat pencils. The top button holds an eraser and unscrews to reveal a lead magazine. These are nearly identical to pencils marked Acme (the clip is slightly different). All of these are marked "Pat. Pend."
The quality on these is very high. The lower example, with the price tag still on it, is in "green gold." The tag indicates the price was $6.00, making it nearly as costly as a $7 Parker Big Red pen!
