Only in Japan could they come up with such a thing. Japanese linen company, Kamei sells the Boyfirend’s Arm Pillow "designed to cradle the lonely sleeper".
The site lists these advantages over a real boyfriend:
Can’t hold a beer or remote
Won’t be out drinking at a karoke/strip club with his co-workers until all hours
Not a two-timer
No more chewing your arm off to get away in the morning
Much more comfortable than a boyfriend’s arm
One size fits all
Optional vibrating alarm clock to put in sleeve to wake you in the morning
Reusable, easy and safe to use. Comes in 3 colors and white.
Almost as ridiculous as their other product the "Girlfriend Lap Pillow".
