Are they all glossy? I don't see an option where you can order them glossy or matte, so I'm thinking that they are all glossy. I have designed a few that have blank spots where I will fill in info- i.e. "Thank you for booking a show" where I'll fill in the show date/time and "Your Past Host Discount is about to expire!" where I'll fill in their past host ID and the expiration date. Just wanted to be prepared as to what type of pen/marker I should have on hand for these if it's going to be a pain TIA!
