Yup, they are Barbie brushes.
Those look like good ol' Barbie brushes to me. You could get enough of them to fill a bathtub! I like the green-colored one.
*giggle* this is so true! I think these things breed when you turn your back on them. Its that or I have accidentally started a rescue society for them without even realising that they show up in every single pony lot I buy.
Me too lol!!! I always end up with lots of these brushes, always pink ones!
