This swallow design is large and each die will have to be made the old way to keep as much of the original design as possible. That's why Kevin is only making a limited number of these dies.
Image that shows depth is an estimated 9mm. Kevin will attempt to make the impressions as deep as possible.
There is a minimal amount of detail lost in the wing section near the head. You can view it in the image of the impression die in the listing.
Design: 2-3/4" x 1-3/16"
