Baseball Badge Set of 4 - Vintage, Original Item, Bonus, MLB-style, Hard to Find

This is a set of 4 retro baseball design badges, said to have been included with snacks and other items during the Heisei era.
With a unique design and color scheme not found in current products, these are valuable items that allow you to feel the atmosphere of that time.
They are rarely circulated today, making them a highly rare item for collection purposes.
The MLB-style design (reminiscent of the Mets, Royals, etc.) makes them recommended for fans of retro雑貨 (zakka - miscellaneous goods) and sports merchandise.

[Condition]

*Please understand that there may be minor scuffs and scratches (see photos).
This item is being sold due to collection downsizing.
It is rare to find these available as a set, so please consider this opportunity.
