I love it! You can easily fit 2 cards in one slot and there is an opening at the top for cash.  It is small and doesn't take up a lot of space.  That is exactly what I was looking for.  It is perfect for my x-small purse and it even fits in my back pocket if needed. Great for the minimalist! I bought one for the cards I use all the time. Liked it so much I purchased another for my extra, rarely used card.
