If you're unsure if it's a 100% het, don't sell it as one. If you got it out of a visual to nonvisual pairing, then it is assuredly a 100% het.
I remember Brian at BHB going through this one time, after three owners and like two or three clutches it hadn't proved out. The third owner actually went after Brian for it and he honored it. Now, what's a couple hundred dollars to him in the grand scheme of things? Maybe not much. But, don't buy hets if you aren't willing to roll the dice.
I've got a pair of 100% het VPI axanthics, any nonvisual animals from the pairing are pet quality normals. I won't take that chance of someone expecting a 66% het to prove out.
