Its crazy to find something from the Xiaomi Youpin Online store but since its cheap, I just bought them anyways.
Mi Joy is another ecosystem supported by Xiaomi in their Youpin Platform and here are some of the items I got from them.
Calculator, Tape Dispenser, Organizer and Stapler.
These are just ordinary stuffs that are available in any ordinary bookstore, its just that it is quite neat to look at. I love the Stapler the most as you can hide one refill under the bottom cabin for that emergency purpose when you bring it outside.
Check out the photos i have here.
