Vintage collector He-man lunchbox. Made of metal. I used to use it as my soldering kit when i was in uni (hence the couple drips of metal inside), and then i used it to store my seeds.
Condition is shown in the picture. Minor wear, tho there is one round dent under the handle. No idea how that dent happened, its a perfect half sphere. Was it always there? I dont remember. No thermos.
