All Pokemon Card Packs come in all different shapes and sizes. They come in tins with designs on them to help you remember which set you have. If you are looking for a box to take to your trading nights, there are options out there for you. They can hold about 50-60 cards per pack. I also have packs that are 10 cards per pack.
