The Most Bizarre Things People Are Actually Selling on Facebook Marketplace

"Brand New" Empty Boxes

At first glance, these listings seem reasonable. Then you read the fine print. Sellers frequently advertise "Brand New iPhone Box" or "Limited Edition Sneaker Box – No Shoes Included" for prices ranging from five to twenty dollars. The logic, as explained in the posts, is that the box is "perfect for display or storage." The unspoken truth, however, is that some buyers may use them for less honest purposes. Either way, listing a piece of cardboard as a collectible requires a certain kind of confidence.

A Jar of "Mystery Air"

Every so often, a listing appears for a sealed mason jar containing absolutely nothing visible. The seller will claim it holds "air from a famous concert" or "the last breath of winter." Prices vary wildly, from a humorous five dollars to a surprisingly serious fifty. There is no way to verify the contents, which is precisely the point. Buyers aren't paying for oxygen. They are paying for a story, a joke, or perhaps just the chance to own something that deliberately makes no sense.

Used Toilet Paper Holders (Still Installed)

Some sellers do not bother to remove the item before photographing it. Listings for bathroom fixtures often show the holder still mounted on a stained wall, sometimes with a roll still attached. The description will read something like "Good condition, works fine, just redecorating." The line between "used" and "still in use" becomes blurry. What is even stranger is that these items occasionally receive offers, suggesting that someone, somewhere, does not mind where their hardware has been.

Free "Bad Vibes"

A small but consistent category of listings asks for nothing in return. A seller will offer "Free Bad Luck Charm" or "Used Negative Energy – You Take." The item pictured is often a cracked coffee mug, a single rusty nail, or a crumpled photograph. The description warns that the object has "a history" but refuses to elaborate. Whether these posts are performance art, genuine superstition, or simply a way to dispose of trash with theatrical flair remains unclear. What is clear is that people keep clicking on them.
