The DMOG has 2 different kinds of screws if I remember correctly:
6×Battery & Board screws
4×Shell screws
The Pen OG has 3 different kinds of screws.
2×Battery Cover screws
8×Shell and Board screws
2×Pendulum screws
What are these screws called?
I found a Website selling cheap replacements, but the shipping is expensive, so I am hoping to buy them from my own country.
