yes-no pillow
Yes-No pillows are matching pillows. One pillow is blue, and the other is pink. "Yes" and "No" are each written on the sides of the pillows.
These were presented as a prize to the couple who appeared in the talk show, "新婚さんいらっしゃい! (Shinkon-san, Irasshai! - Welcome, newlyweds!)". The program presenter never told how to use it, though it is probably used for the declaration of sexual intention.
Depending on which side is visible in an image, add the yes or no tag. Both tags may apply if there’s more than one pillow.
