I was surprised because the size came out a little small haha. But it's a little small so it fits well in my ear, which is good. After I requested the design, I was worried because they told me over the phone that there would be a lot of difference between the product and my requested design, but after the product came out, I clearly understood the manufacturing principle that they mentioned. Next time I make a request, I will order a design that takes more into consideration the premise that it will be worn on a mask ^^
