Received last week and finally took the time to build it last night.
Switches are Gat X with 57g TX springs, using a pp plate, cherry clip in stabs, and PBT Spellbook for caps.
I'm trying out gummy o-ring mount first since I've never used it before, feels pretty good but I'll probably switch to top mount in a few days to feel the difference.

(I hope kbin supports multiple image posts soon so I don't have to do this anymore)
I don't think they mean anything, they are just "magical runes".
The box the set comes in also looks like a spellbook, it's all pretty on theme.
