The correct term for these are German Machine made Slag, although you will see some descriptions or titles say striped transparent. That would be a term used for Christensens. A lovely one from my keepers, almost peewee in size which in my experience, having had a lot of these, is harder to come by. Extememly well designed with a thick and detailed pattern on both sides of each seam. Definitely more of a light orange colour than Amber Shows as Mint in hand but under loupe a small scuff/pin patch in the white
