Although swallows, swifts & the like are happy to see seeds & breadcrumbs put out for them, the ones on this Kingfisher & Insect Eaters 1/2 Pint Mug definitely look intent on spotting a juicy grub. What is a second? All pottery is inspected before it leaves the factory. When an item is classified as a second the fault or faults may be in the finish, the decoration or the shape. The faults are not structural (i.e. each piece still functions as intended & is useable). Faults are marked with a black line which will be visible when your product arrives but washes off with a damp cloth. Discounts cannot be used in conjunction with any seconds, discontinued or sale pieces.
