After the campaign ends, you will receive a survey from Backerkit that includes the option to add additional items to your "cart". This is where you will be able to access the Add-On store. Most of our reward tiers will be available as Add-Ons, with the exception of the resin pieces.
All Resin Pieces are only available through the campaign reward tiers, and will not be available as Add-Ons. So if you are hoping to get the resin moon and a print, you would need to back the project under the Resin Moon reward tiers, and then Add-On the print during the survey process.
Now, all of the prints and various sizes that we offer will be available as Add-Ons! We will also offer any variation of book that we offer during the campaign (There may be larger sizes coming later ;) ).
If you have any further questions regarding the Add-On store, please reach out to us and we would be glad to help!
