I believe this is an antique bathroom set. There's the toothbrush holder, the swan towel holder, the soap dish, and. . .
. . .the bunny cotton ball holder, lol. I laughed so when I saw the bunny butt that I had to spend the $1.50 to purchase the set, just for the laugh. I really have no idea how much the set is worth, if it's even worth anything, but it brought a smile to me and I thought it might you too.
