My initial comment had a snarky bit about women's razors that I removed - because for me, "women's razors" were those stupid round-flat Tylenol-shaped things that were about as anti-ergonomic as humanly possible. Every girl I've dated since the mid '90s has used a men's handle in the shower and when we've discussed why, they've (to a woman) said "yeah, women's razors are shit."
But in looking at womens' razors these days, they mostly seem to be men's razors with slightly blobbier handles and/or slightly pinker colors.
I can see why "pens for women" ended poorly - there's nothing inherently masculine about the coloration of a pen. Health and beauty products? Oh, fuck yeah. I've watched half of the skin care aisle at BBB turn black over the past 10 years as companies discover they can sell moisturizer, buff puffs, lotion and hairspray to men if they put it in a nice butch container.
I've used Oxy pads since I was 14 (bad news, kidz - you still get zits at 40). They used to be in a white and pastel container. Then about '04 they started looking like something Rambo would keep hand grenades in.
