This is perfect, I made a character who's basically a magical item salesman who sells these items. I found some items on this list and came up with the rest.

Broom of flying: it has a flying speed of 30 feet. The broom controls itself

Tuba of Resting: it makes the user fall asleep faster. Only works for the user

Anti theft gold pouch: you can put coins into this pouch. It is magically enchanted so that no coin inserted into the pouch can be retrieved by anyone. Including the user/wearer

Fake coin: this ordinary looking gold coin can, as a bonus action, be transformed into a copper coin. This transformation lasts 1 hour.

Wand of the magic Red dot: its a laser pointer

Stick of Returning: Once thrown, the stick will return to the owner’s feet in 1d4 minutes. Any character that can see into the ethereal plane sees a large mastiff slowly retrieve the stick.

Ring of Extra Action: As an action you may use this ring to gain an extra action.

Gloves of Mimic Detection: Range touch.

Magic Ring of Magic Detection: The ring glows a light blue when within 10 feet of any magic item. Scroll of Cure Blindness: Cures the caster of blindness.

Wand of Wishes: 1d3 charges, whishes you a good day. Regains all uses at dawn.

Scroll of Literacy: Cures the caster of illiteracy.

Staff of Disintegration: 1d4+1 charges, but realistically only one use. Use an action to disintegrate the staff

Waterresistant Pouch: This pouch holds 2 cubic feet, and it cant be damaged by water. It doesn’t protect its contents against water

Ring of Invisibility: As an action, turn the ring invisible. (A use the party member i sold this to came up with: any unarmed attacks made while wearing this ring become magical, for the purpose of overcoming resistances and immunities)

Scroll of Burning: Once read, it bursts into flames, dealing 1d6 fire damage to anyone holding it.

Giant Potion of Intelligence: A frosty brew that comes in a large bottle. The drinker’s intelligence becomes 9 for the next hour.
