Based on the product name, the Black Butler Tete Collection by GSI Creos is a series of collectible, stylized figures.

Here is a detailed description:

• Product Type: The term "Tete" refers to a type of figure with a large head and small body, giving it a chibi or super-deformed appearance. These are small, non-articulated figures made of PVC.

• Franchise: The collection features characters from the popular anime and manga series Black Butler.

• Packaging: The figures are typically sold in blind box format, meaning you do not know which character is inside until you open the box.

• Characters: A full collection set usually consists of six figures, including key characters such as Sebastian Michaelis, Ciel Phantomhive, Undertaker, and Grell Sutcliff. The other figures in the set are often "secret" or "hidden" characters.

• Size: These figures are very small, usually standing around 5 cm (approximately 2 inches) tall.
