This is Yuzawaya's "Squeaker B-6, Pack of 2" B1-JA(a29)! For handmade stuffed animals, knitted toys, etc.! These are squeakers to put inside stuffed animals. They make a "peep peep" sound when pressed. I purchased these and stored them without using them. I will not be using them in the future, so I am selling them (^-^)
