Will the new key chains be available as add-ons at a future date?

Do the bags themselves come with one insert and the add-ons are for exclusively "extra" ones or do you need to buy an insert for the bags in order to receive any?

Maybe I just can't read lol but I was looking thru instagram and couldn't find it. Will the Demon Stolas bag be added as an add-on at a later date, now that the stretch goal has been reached? He's to DIE for! :D

Is there an estimated timeframe for the sample/prototype for the large stolas bag? Will his face will be white like the concept art, or grey like the small bag?
