Flatsys have long hair, which goes to the floor, generally in vivid colors (like bright blue, bright yellow, pink, etc.). They are made of soft vinyl with wires inside the limbs, neck, and body, which make them posable. Their faces have sweet, grinning expressions with eyes looking either to the left or to the right. The packaging the Flatsy doll is sold in can be used as a decorative picture frame, and the doll is also possible to wear as a pin. In 1969 when Flatsy retailed for $3
Corpus Christi Times described it as "reasonably priced". Each Flatsy has a "theme" and comes with an accessory and a cardboard liner with a picture in keeping with that theme. They also have a plastic clip to hold the doll in place on the liner card, which also detached for play time. Commercials for Flatsys featured the theme song: "She's Flat and All That!." Flats Dolls wear "
mod" clothes reflecting the styles of the 1960s. Every Flatsy came with shoes and, in nearly every case, a hat. == Sizes ==
