This is what I sent:
The hat box arrived and I'm quite happy with it, but I felt I really need to talk to you about the fact that it was packed in R16 house insulation. I don't know if you are aware that it can hurt people like me with eczema and other skin troubles. This stuff has to be handled wearing protective clothing, glasses and gloves and unfortunately, I had my hands in it before I realized what it was. Please don't ever use this as a packing material for your future transactions, you are likely to end up not only with negative feedback, but potentially paying for a visit to the doctor!
