I'd better keep my trap shut about flaws in these, though I do know bubbles shouldn't really be there.
However, I think to get shot of it, go with the what you did before - describe the bubbles, show them in your pictures, include the box if you still have it, etc.etc.
Butterflies are popular, this one has red aventurine in it (the sparkly body) - nice feature to have.
Should sell no problem, just like the last one!
