Blu-ray Disc Case in One

I love the medical drama Doctor House.The main character, Dr. House, a toxic genius, is so cool.
It's a great way to learn about medicine, so I decided to keep the Blu-ray discs instead of throwing them away. But the box takes up a lot of space, so I decided to store them in a Muji holder.
I thought I bought one that holds 40 discs, but I mistakenly bought one that holds 80, lol.But thanks to that I was able to store all the discs in the house in one file.
