At least, that's what I'm assuming the market research showed that lead Nerf to develop this product...
To quote my friend who emailed me about this:
Because clearly there was an underrepresented market of female friendly fashionable Nerf guns. If you're going to be daring and do some ruff and tumble action, style is essential.
So if you wanted to get your little girl a Nerf gun for Xmas, but were concerned she wouldn't want to play with it unless it were pink, problem solved!
Back in my day, we didn't need no stinkin' gendered Nerf guns...I was perfectly fine stealing my brothers'! It was funny...they had no interest in stealing my American Girl dolls, but I was all about arming myself with their Nerf guns and Koosh balls...FOR SWEET REVENGE!
