Our threadless Paw Prints from Industrial Strength are made with Swarovski crystals or opals. $10 from every purchase of the paw prints, a donation is made to a no-kill animal shelter.  All of our threadless offerings are safe for initial piercings. Threadless jewelry is an innovative approach to threaded jewelry, but just as reliable with the right bend by our professional piercers are compatible with industry standard threadless backings.
