Here is the instruction online: https://www.instructables.com/id/Leather-Card-Case/
We developed some Acrylic templates, by using it, you no need to draw lines on the leather, just use knife to cut leather directly, save you some time.
But we should admit that acrylic pattern is not as detailed as downloadable pattern, downloadable pattern has more hits on it.
There are some Chinese words burned on the acrylic patterns, the reason why because the software of the laser cut machine can't support English, but the instruction will help you.
We use 2.0mm acrylic board, after lots of test, 2.0mm is the best thickness.
For this pattern:
The size is about: 3.1" x 3.9" x 2.2" (8cm x 10cm).
Leather: We advice 2.0mm (5oz) leather, size 25cm x 25cm.
Hardware: No need.
If there is no in store, we normally need 2-3 days to product, please be patient, thank you!
