[Product Condition]
- New, unused, and unopened.
- Kept in its original packaging bag in a dark place.
- As this is a vintage item (deadstock) from that era, the packaging may show some age-related wrinkles and scuffs, but the pens themselves are in excellent condition. It is also perfect as a collectible, preserving the atmosphere of the time.

This is a great opportunity for collectors of discontinued stationery or for those who have been searching for this item. This is a very rare set of three colors.

[Shipping]
As this is a very valuable vintage item, it will be shipped with reinforced cardboard and cushioning material (bubble wrap) for waterproofing and to prevent the packaging from being bent or crushed during transit.

*Please only bid if you understand vintage and retro stationery.
*No claims or returns to prevent fraud.

Thank you!
