What kind of drawing is on the back of the My Family Tumbler?

The Ishizuka Glass My Family Tumbler features different drawings on the front and back. A soft pastel-toned cat face is placed on the front, and when turned to the back, a slender cat tail follows^[1]. It is a composition that utilizes the curved surface so that the front and back face each other within a single glass.

The outer surface of the glass is processed using a sandblasting technique^[2]. Sandblasting is a method of spraying sand under strong pressure to shave the outer surface of the glass, creating a translucent color and a matte texture. Because this finely refined matte surface is prone to scratches when rubbed against hard tables or floors, it is advisable to take care when setting down or washing the glass^[3].

Because the drawings are applied by hand, the angle of the cat's face or the left-right symmetry may appear slightly tilted on each glass^[4]. This is not a defect, but a natural difference that occurs in each piece when glass is processed by hand^[5].

hmmm, it is a detail that offers the fun of feeling like you are alternately petting the front and back of a cat each time you hold it in your hand and drink.
