These are gridfinity-compatible, stackable, lock pick cases for Jimy Longs lock picks. 

Two variants are provided: One with the finger cutout at the bottom, which makes removal easier but is somewhat looser. The other has the cutout in the middle for a tighter fit.

The case is Gridfinity compatible but at twice the pitch (i.e., 21mm x 21mm squares rather than 42mm x 42mm). The case itself measures 2.5 x 3.5 Gridfinity units.

The case provides holes for magnets (they are basically required) –- especially to retain the picks. I used 5mm x 2mm circular magnets (these are actually 5mm in diameter, but 1.76mm tall). The specific magnets I used are: [https://www.amazon.com/dp/B0CCXY6WBR](https://www.amazon.com/dp/B0CCXY6WBR)
