Burn the tip of a sharp knife or fork tip until red hot, then melt that sucker back together.
Also, pics of sister?
Not enough information to solve this problem. Need pics of sis.
There's a wire inside the plastic, no fix needed.
That may be. I've suspected it, but I just can't tell. She definitely doesn't want to lose the piece.
Even if the plastic cracks all the way around, it will not just fall off. The plastic is bonded to the wire. Trust me, I've worn glasses longer than you or your sister have been alive.![]()
