Hi!
It's just a piece of fibreglass! Any insulating material would work -- even a thin 3d printed piece of PLA can be okay depending on your finger. Ideally we would use glass pieces, but in the end it was easier to just use thin copperless PCBs (i.e. fibreglass) wthl silkscreened markings. Maybe one day we will work out a good supplier for glass covers and switch to them, but it's pretty far down on our todo lists.
