I can put fairly large earrings in it (it just makes it a little tricky to see what's below them) as well as hoops and studs. I did notice that I cannot use it to store fluffy earrings or overly large hoops. But I don't have many of those and had planned to store them elsewhere anyway.
One thing to note to make adding earrings easier - there are little notches at the top and bottom of each row. Angle the base of the earring hook toward those notches while adding your earrings. It took me a whole row of forcing earrings into the holes to realize what those were for. 😂🙈 And I do notice that some of the earrings are easier to remove by pushing the post from the back.
Overall, I love this product and highly recommend.
