Okay, imagine you are playing with your toys at home and you see a Christmas market has appeared outside. But instead of staying the whole year, it's only there for a few days. This type of store is called a pop-up shop!
It's a special kind of store that appears suddenly in a place where there wasn't a store before, and then disappears after a short time. Usually, they are smaller than regular stores and only sell a certain type of thing.
Sometimes, well-known brands will use pop-up shops to showcase their new products or test out new markets. Pop-up shops can also offer unique experiences like special events, workshops, or limited-edition items.
So, to sum up, a pop-up shop is a short-term store that sells a certain type of thing and gives you a unique shopping experience!
