Ordering your Secret Lab Stickers is the easy part. The fun part is adding your own great decorating ideas when using them! You can use our special stickers inside treat bags for your guests, on a glass jar filled with candy and tied with a ribbon, or any favor container filled with treats. You can also use them to seal your invitations or thank you notes. Party sticker labels and envelope seals make your do-it-yourself projects a piece of cake!
