I bought this sticker kit at a Borders store. I am very pleased with it, except that Hedwig's eyes are orange. Hedwig is not removable from the cage. The cage as a whole weighs 2.1 ounces or 59 grams. The cage is 3.25 inches or about 8 centimeters tall. The base is 1.75 inches or 4.6 centimeters in diameter. The cage has a loop on top that would be ideal for attaching a hook to, in order to change it to a Christmas tree ornament. The sticker book contains 8 stickers that are each 2.25 inches by 1.75 inches or 5.6 cm by 4.6 cm. All of the stickers are of Hedwig or Hedwig and Harry. Overall, it is a very nice knick knack to have.
