$50 with a pen $40 for refills
You gotta check these guys out!!
If you're gonna buy their Shatter: WARNING:
it turns sugared up after a month or so, don't buy too much!! It's still good though!! Very good!
I prefer the pens now, it's instant with no mess, it couldn't get any better or easier!
Extra's (magnet to make pen stand on metal disc for sturday table usage):
Small Multi-Use Magnets (magnets used in picture are 8mm x 2mm but they're a bit small)
Metal Discs
You will need some (super?) glue too!
