Query: Worst possible Quality

The fabric of the costume disintegrated on the first day - a big disappointment. It is very, very cheap and thin. The mask (it's not a helmet!) is an utter disgrace and the kids did not like to wear it at all. Absolutely not worth even half the price you'd pay on big sale.I will contact Amazon CS about it - but we would not want to receive a replacement. I would rather just throw this out and write it off under 'cheap crap from China I should not have bought'.
