I saw some lighters at Walgreens a few weeks ago that were very compact. They were cylindrical, and as I recall about 3/8 to 1/2 inch in diameter, less than 2 inches long. Not a heck of a lot bigger than the spark-lite, IIRC. No guard on the flint wheel. I should have grabbed a few, but that wasn't my mission. Next time I'm there I'll get some and tell you more.
