Sheaffer’s Mechanical Pencil Store Display Parts Repair Hard Plastic Case. What an incredible find at a recent estate sale. We have found no comparisons but have talked to a few people who have similar or identical cases and as pen and pencil collectors, would not give it up for anything. See photos and ask questions. The case itself weighs almost 12 pounds. Packing will be at least another 3 pounds which may include a box in a box system. Will ship USPS or UPS, whichever buyer prefers, which will include tracking and a Signed Delivery Receipt to protect both buyer and seller. Seller will pay for Delivery Receipt.
