Using CustomMaker and image can be uploaded and made into a seal to use on wax. The seal is 25.4mm (1”) in diameter and 25.4mm (1”) tall. One end has a recess for making the impression based on the uploaded image. The image can be scaled and move after uploading.
THE IMPRESSION MADE BY THE SEAL WILL BE A MIRROR OF THE IMAGE, MIRROR THE IMAGE BEFORE UPLOADING.
