Hi Deborah, Thanks for contacting us. You can absolutely use Ribbet for commercial sales, with the following exceptions:
– The stickers and the frames with sticker elements (such as the flower frame) may require the purchase of one or more stock images. If you would like to make use of these commercially, then let us know specifically which stickers you want to use and we’ll forward you a link for the stock images required.
– Some fonts require a small payment for commercial use (click the little human icon next to the Add / Delete buttons on the Text tab for a link to the font designer’s website to check on this).
Let us know if you have any questions!
