At this price I'll leave them. Too many repackaging and shipping issues at UPS. They are METRIC, not 1/8 to 3/8 as stated. Although for some jobs it may come close enough. The glasses look as if they were cut by hand and are not very well made. The pins of the large ones are clearly ground unevenly. I'll try them on some reclaimed wood before relying on them. I was hoping for a few lower points for critical work. I think it will not be the same.
