Thanks for clarifying!
@Justin: The polishing cloth will be included with every Vortecon for free. I guess we didn't formulate it correctly;) Probably a more proper title would be "Stretch goal" (that is already reached) or ''Reward upgrade''. Anyways, thanks for mentioning this.
"We will include a special polishing cloth with each Vortecon"
So...is it an add-on or not? Add-on typically means you have to increase your pledge amount to buy it.
