Rare! Found in the warehouse! Mac Tools Mini Car Set Midget Car Long-term stored item

For sale: A Mac Tools die-cast car set.
This is a vintage item, stored for a quarter of a century.
I believe this is a rare item.

It has been stored in a closet in the condition shown in the first image for a long time.
It's likely from before 2000, so it's been almost a quarter of a century.

I took the contents out and photographed them for this listing.
As you can see, the outer box and packaging have yellowing, scratches, fading, and dirt, but the die-cast cars themselves are in good condition.
The rubber parts, such as the tires, may have deteriorated over time.

This is a set of three 1/50 scale midget cars.
I believe these are race cars that run on dirt oval courses in America.
The asymmetrical wings are a distinctive feature, typical of oval course racing.

This item has been stored for a quarter of a century.
We kindly request that you purchase this item only if you understand and accept the above description and images.
