Review on Optimized Memory Card Case - Store and Travel with Ease - Holds up to 22x SD, SDHC, Micro SD, Mini SD, and 4X CF - 22-Slot (8 Page) Holder - Grey by Tyrone Narvaez

2200 reviews for $7 worth of card case! You don't even have to think before you buy it. And like me, you won't regret your purchase. This is a good way to keep all your DS cards in one place. Reasons why it is so popular: 1. The case is made of high quality material. 2. The zipper on the card is pretty smooth and works great. 3. The plastic material inside to make SD card case is durable plastic4. It has 22 card slots, 4 of which are for large cards5. Comes in 5 different colors to match your style! Improvements Needed: The only improvement I can think of is to make it a bit larger so it can also hold CF cards so you don't have to carry a bag around. for SD cards and one for CF cards. But given the price and the benefit you get from carrying all your cards securely in your pocket, I think it's worth the money.
