I'm afraid they didn't have a name! I bought them from a UK company called Axminster. If anyone can tell us what they're called that would be great!!
They are a lovely one-piece twist top. As far as I recall the tubes are 8 or 9mm. They have a Parker style refill. I'm really very pleased and I'll be buying more. My 12 y/o son segmented and turned the near one himself. I finished w/ CA and BLO.
