You are purchasing 6 Tolbunt Polish or Bielefelder hatching eggs. My Tolbunt Polish have GFF and Dave Schwartz's National Champion stock bloodlines. The Bielefelders are from GFF. Fertility has been excellent. I cannot guarantee hatch rate or the handling of the USPS. The buyer will accept the risk of buying shipped eggs. You are guaranteed to receive well packaged but no other offers to refund/replace purchases for conditions outside of our control. Please PM me with any questions. I will only only ship Mon-Wed. Payment is via paypal only. $50 total for 6 eggs and shipping. $90 for 12 eggs and shipping. If you would like a heat pack placed in the box please add an additional $5.
