Very few products appreciate excessive heat natural timber or made products. Especially children, if the car is wrong for children its wrong for pens.

Im totally baffled by this - can only assume its either temperature related or ink leakage (There was some ink inside the cap) - Does anyone know how ebonite should react to moisture / temperature?

by the nature of how ebonite is manufactured it will reshape and deform if exposed to temperatures of above 70.C

I understand that some manufacturing processes use linseed oil, that will also break down with the heat and cause other problems. I guess it will also change when you add ink in to the pot as well.

I think 70°C could be reached on a car dashboard even in our climate, on a sunny day. I know CDs and DVDs will warp if left there.

Good God that's incredible, it must be life threatening for some. At least the truck was fixed for the next summer haha.
