Holds 4 SD cards in my wallet just like a credit card. Helps me go really light for the day. 4 SD cards camera and two extra batteries and set for a day of street photography. Can't get much lighter than that.

The Leica SD card holder is quite the luxury item. I toyed with the idea of purchasing one because I was fairly happy with my current weatherproof molded plastic holder that can store just about any available memory cards on the market. I rode the fence for quite some time because it seemed like such an expensive extravagance just to store several SD cards. After much dilly-dallying, I decided to pull the trigger, primarily because my camera only takes SD cards and the internal rubberized material of the plastic weatherproof case barely held the cards in placemany was the time I found the cards loose, or they'd fall out when i opened said weatherproof case. The Leica SD cardholder is, however, very nice to have. I've managed to stick a few business cards in with the SD cards. The back of the SD card holder does clean the rear LCD screen (or its protector) rather well. The leather has a quality feel about it, reminiscent of the proverbial comfortable shoe. I purchased the black one, and so far I haven't had any trouble fishing it out of my camera bag, even in dimly lit or dark venue situations.

Slim, nice quality, and holds SD 4 cards.

When we travel, we almost always pull our US nanosim and use something we buy in-country for data access. Nanosims fit securely sideways in the microsim slots.

I use this to carry my emergency back up SD cards (The I forgot my cards at home set). It is lightweight and compact. Easy to pack and carry. Fast to access by feel. Although SD cards are very durable, this Card Holder is open and should be packed in a weather resistant location.

The Leica SD and credit card holder is nicely made with the sd card holder slipping snuggly into the credit card pouch. There is room for maybe two cards, e.g. Driver's license and credit card, or use the two parts separately. Would have liked an eye-hole in the sd sleeve to secure it to my bag, but, this works well in a small side pocket.

ok, i admit it ... this is kind of fashionable, but ACTUALLY i was looking for something that offer good protection for several cards and DO NOT TAKE MUCH space , so this is a great fit.
i have a small gopro bag , pretty compact, and this holder rest FLAT at the bottom taking almost ZERO space while storing and protecting up to 12 cards. I think it is expensive, but saved me tons of space ...

I use it for travel, and it's compact design is great. I also have the yellow one for my extra cards, and use this one for the full cards. It's compact and saves a lot of space. SD cards are very durable, and these holders keep them organized without taking up a lot of bag space.

These SD cases are well designed and of high quality as would be expected on Leica products.

Love it, its perfect to keep your cards organized and from flying around in your bag
