This is a hat pin with an airplane motif. I purchased it new and have hardly used it. It's also stylish as a tie pin or lapel pin. There is a star mark and an inscription that appears to read "pt950" on the back of the aircraft, so it is believed to be 95% platinum (although it is difficult to see in the photo due to the small inscription...) You can use it on hats, jacket collars, or as a tie pin. ✴︎Currently, the value of platinum continues to rise and is expected to increase in value in the future. The entire pin badge weighs 3.6g, and the aircraft alone weighs 2.3g. ★★★If the box and the pin match, it is believed to be an original hat pin from a hat shop in Ginza, but the details are unknown as there are no records. Also, although there is an inscription, it has not been appraised. ---Please consider purchasing the above, understanding the above--. ✴︎For collectors of airplane-themed goods and those looking for platinum. No smoking, no pets. We will deliver it with Mercari's anonymous delivery service. Please understand that we will use simple packaging. We will ship as quickly as possible if time allows.
