I ended up buying another one of these! The holes don?t line up so I can?t stick a 3. This was way bigger than I expected. I was going to use these foam pads with my AirPods but they are a little bit thick so my AirPods sometimes dont work when I put them on my ears (without them, they know they are on my ears). However, now the printer is informing me that my black ink is low. You dont even need the simple instructional drawing. great for the price. I put the back of the van up on jack stands, took off the passenger side rear tire and went to work. I?ve worn them to work a couple times when my feet were sore and they didn?t look out of place. They are pretty cute and quite comfortable!
