Will you be re-stocking a keycap set from a pre-order?
It is typically not up to us as the vendor if a keycap set will get another round of production. This is usually up to the designer(s) of the specific set. Checking the GeekHack page for the set is the best way to stay up to date and express interest in another production round.
Once the limited extras are sold out, we will not be re-stocking them unless they are produced again.
