Why does Disney's Lina Bell only sell one or two pieces?

Generally speaking, Disney's only holiday-limited goods will be restricted because of the limited number of sales, and Lingnabel has become this "special case". The official customer service staff of Shanghai Disneyland said that although the products launched by Ling nabil are conventional products, they are too popular, so each piece of Ling nabil series products is limited to two pieces, depending on the quantity later.
