These are the buttons you've been looking for if you're planning a super-mini-game project, or want some arcade-looking, but smaller admin buttons.  They are black only, and are a dead color & texture match for regular black arcade buttons.  Switch (integrated), nut, and washer are included.  I have a limited supply of these for sale at 
$1.39 each. Why do all the prices end in 9?  Damn, that's eerie.  Make that $1.40 each, plus shipping.  
Edit- The most shipping has been so far is $2.34, to send 16 buttons from CA to NJ.Order via PM, please.  Yes, I take paypal.  Or money orders, or gold bullion, or Major Havoc rollers- whatever's easy for you.  If you send me your address with your order, I can get your shipping quote faster.
