Operated by a foot treadle. I've had this machine for about 25 years, during which it has produced around 10,000 5.8cm badges. At times it is like printing money but it doesn't get so much use now and takes up space. Simple to operate with a bit of practice. Parts per badges cost 40c - 80c, readily obtainable on Trademe. You can sell badges for whatever you want but mine have been sold to return about $1 profit. Very robust machine. Comes with my remaining stock of badge parts (fronts, back and mylar covers) Great for fairs where kids make their own badges, class name badges, events, political campaigns, business promotions etc. Great sidekick for someone who wants to promote it as a business. Reserve $300. Obviously heavy and shipping is likely to be expensive. Also a few lessons on it will be helpful so pick-up by van, ute or station wagon is best.
