The card holder sleeve.

For the past months, I had been sending card holder sleeves to different part of the World.
And it got many people curious about the card holders that I've been sending.

So here's a little introduction about the Card Holder Sleeve.

There are 5 slots on each size.
Personally, I put 2 business cards into each of those slots (as seen on the left),
and the necessary cards on the right.
