Mini Glock Case by Nofsky Industries

Got my Mini Glock from aliexpress

Some are better than others when it comes to quality. I opted for the bullet eject option and got an extra mag and bullets.
mine also came with a foam cutout and a mini holster, although it was not stated anywhere, just a nice freebie!

Use a 3mm x 90mm pin for the case hinge, and (4) 5x3 magnets
