When one speaks of items with mystical properties, it is commonly assumed that they look antiquated enough, bearing associations with either ancient civilizations, the Middle Ages or some other time period no later than late 19-early 20 century (like magical staffs, manuscripts, mirrors, potions, etc.). This trope, instead, is about paranormal items that look like they were bought in a shop nearby. They would usually be labeled with either an unfamiliar trademark or a familiar trademark with a strangely altered label. For example, it may be a chocolate bar which would transform you into a monster if you eat it or a video game cartridge that would teleport you into the game's realm as soon as you put it into your console.
Such items can often be found in Urban Fantasy, may be used by a Blue-Collar Warlock, and are frequently sold in a Little Shop That Wasnt There Yesterday. Often overlaps with May Contain Evil; also compare Haunted Technology.
- The Goosebumps series have lots of those:
- Full Moon Fever has chocolate bars called "Best" (actually "Beast"; turns people into werewolves) and "Cure" (actually "Curse"; makes people shrink in size) that look like your everyday shop merchandise.
- The Monster Blood from the eponymous book is a jar of weird green substance that looks like children's slime toys, but has very creepy magical properties.
- Beware of the Purple Peanut Butter has the titular purple butter that makes you shrink, and a piece of cake that makes you grow in size.
- In Shop Till You Drop ... Dead!, the protagonists are on a Scavenger Hunt to find a number of items in a night department store. Goods found in this store include among the rest a Heart-Attack Backpack that suffocates people until they have a heart attack, and a toy ape that comes to life at night.
- In Scream Shop series by Tracey West, Sebastian Cream's Curiosity Shop specializes in selling such objects. One of the notable examples from The Curse of Count Blood is a vial with the symbol of a comic book character which turns out to be a tool for resurrecting staked vampires. Of course, as the main character quickly finds out, in his world Comic Books Are Real...
- Robert Sheckley's "Fishing Season" centers around food items that look very similar to usual grocery products, but have some strange minor differences. They actually serve as a "bait" for humans, and those who eat them are sucked into another world.
- The portkeys in Harry Potter are seemingly meaningless pieces of trash, like an old boot. Deliberately averted with horcruxes, however: Harry asks if they could be anything, citing the portkeys, and Dumbledore replies that they could be, but any wizard vain or evil enough to make one, like Voldemort, would never lower themselves to put a piece of their soul in something easily mistaken for garbage.
- Warehouse 13 involves many items that may have been run-of-the-mill when they were first made, but because they were owned by historically important people they ended up obtaining paranormal powers (or maybe the historically important people became such because they have paranormal powers; the series is glad to leave either option in the air).
- The Objects in The Lost Room are perfectly ordinary-seeming items with bizarre and unintuitive powers, like a comb that can stop time, a canteen that causes everyone nearby except its holder to asphyxiate, and a pair of scissors that forcibly turns whatever they point at around any axis. They were originally entirely mundane items that were part of a man's luggage within the titular room when a mysterious Event transformed them, and they have since been disseminated around the world as people fought over them. The Objects are also indestructible, except when inside the Room itself.
- Friday the 13th: The Series revolves around the objects of a certain store that held paranormal properties (and some of them were quite modern-looking, like a radio), but all of them were a pretty vile Power at a Price (as an example: a crucifix that allowed even people who knew nothing of spiritism to perform exorcisms, but had to be fed human blood (and that meant stabbing people dead with it)), a scalpel that would insta-heal whoever it was used on in an operation (but required it to be charged up by killing someone), a wheelchair that gave the capacity for Astral Projection to whoever used it, and the like.
- Buffy the Vampire Slayer had supernatural power invested twice into mundane comestibles, creating candy bars that made you act like a teenager and beer that turned you into a caveman.
- The d20 Modern setting Urban Arcana has multiple examples of these kind of items within its gear section, from a chainsaw that gave its user a capacity to summon berserker rage in combat, a car bumper that gave the car it was attached to the capacity to ram with the strength of an even bigger car (so a Sports-Utility Vehicle would be hitting with the power of an eighteen-wheeler), a cell phone that had literal Super Cell Reception and could dial the phone nearest to anybody the user wanted to contact (if that person didn't had a phone of their own), and the like.
- Sam & Max: The Devil's Playhouse centers around the mystical Toys of Power which are actually very ancient, but for some reason look like ordinary toys that may be found in a modern-day toy shop (like a toy telephone that allows its user to teleport and a wacky putty toy that gives him the ability of transformation).
- Whateley Universe: Ms. Grimes's reliquary (storage device for magical energy) is a bowling ball bag.
- SCP Foundation: A decent number of artifacts contained by the Foundation bear some resemblance to some form of product intended to be sold to the public, to the detriment of anyone unfortunate enough to find one. In addition, there are a number of organizations of interest that specialize in the production and or sale of such artifacts.
- Dr. Wondertainment is a person and or company dedicated to making anomalous toys, with less than stellar standards of product safety.
- The Factory is a factory in an unknown location that mass produces anomalous appliances with guaranteed sinister motives.
- Marshal, Carter, and Dark is a black market club that seeks out such items to sell to its clientele. They take great care that their products do not harm their owners, but the same can't be said for what the artifacts may require in order to function.
- SCP-261 is a vending machine that sells a number food items similar to the real-world trademarks, but with some really bizarre properties.
- The non-living merchandise from The Awesome Store in The Amazing World of Gumball are magic items that look like mundane appliances:
- "The Disaster" and "The Rerun" featured a TV remote which controlled real life.
- "The Console" is about a knockoff portable gaming system that turns Elmore into an RPG. In the same episode, the store also sold a bag of fertilizer that turned Leslie into a giant Man-Eating Plant, and a cellphone that forcibly turned Penny into a violent cyborg.
- "The Shippening" features many household items with magic powers, most significantly a regular notebook (with a Cartoon Network logo) that allows Rewriting Reality.
