Four bassinet mattress cover protectors - white

never used, just opened and washed because I tried putting them on our Ingenuity Dream Hero bassinet mattress which is a large rectangle, and they do not fit. They are for an oval or hourglass bassinet - 32x16 fit, but last photo shows that they are universal so they can fit other dimensions as well. Two different brands, two of each brand. (All four are the same size). I bought the two Youfoss myself on Amazon and the other two were gifted to me, brand is Biloban.
