Understandably many gift ware manufacturers do not care to be identified to the second user market.
But in this case we have a respected pottery using a quality indicator that is readily removed and replaced to enhance value of their own products in the after market. Perhaps, cynical but possibly a good move for shifting large quantities of the seconds to the second use trade who can easily obtain the upgrade buttons. It would also tie in with accountancy practises/philosophies of the modern era.
