This is v2 of my microSD card holder. Depending on the adapter you need for your PC, you have to select the right bottom part.

As the adapter for USB-C got smaller, the box is smaller as well. For standard USB the box is a little taller to fit the new adapter.

Space for up to 12 microSD cards, microSD to SD adapter, microSD to USB/USB-C adapter.

The first bottom part is for a USB-C adapter.

The second bottom part is for a normal USB adapter.
