How long does an average package from Hong Kong to Ireland take when it's being sent my normal airmail?

I recently made an order on Deal Extreme a gadget website based in Hong Kong and I ordered some headphones some sunglasses and a lighter, my order was dispatched on the 18th (yesterday) by normal Hong Kong Airmail. I am in Wicklow in Ireland close to Dublin, Does anyone know how long it will take until I receive my order? Thanks
