Molded Fingerprints:Molded fingerprints are just that, a mold of a finger.  So, they are best if, for example, you'd like to have your children's finger shape and size at this point/age in their life to preserve.  I personally, have taken my children's molded fingerprints every other year, and the depth of the lines and size of their mold will be different each time. Fingerprint molds for children don't typically have very deep lines, and if a child is under 3 year old, they may not be very visible if at all.  They are still great to have a mold of their little finger to preserve as a keepsake. The mold you create for me is the mold I use for your fingerprints.  The better the mold, obviously, the better the finished piece will be.  That is why I provide detailed instructions and a video is available to you as well for a good visual.If it's more important for you to have more visible fingerprint lines, it's be to choose the option "Fingerprints on Paper".Fingerprints from ink/ Fingerprints from a Jpeg are our best sellers and a terrific option if: 1. Time is an issue, these pieces can be made relatively quickly if needed, as molds do not have to be sent back and forth in the mail. 2. You'd prefer more detailed fingerprint lines.3. Allow multiple shape and sizing options.4. If you are outside of the US or Canada, as everything is sent via email. There are no need for molds to ship back and forth, which is very difficult with customs.5. If a person has passed away.6. Overall, this is the best option for any fingerprint, as it's more controlled, and I create the mold from paper for you so there is less room for error.
