I'm still on the last thread so sorry if this has been mentioned...
Does Pears soap contain palm oil?
Anyway, triangulate me (can't find the triangle emoji) but in the 90s, I used to work for the label/card company that made the Imperial leather label. We did all the quality control testing and had a machine that just constantly rubbed the soap and label to see if it stayed on and passed the tests. No one at that company could bear to use the soap as that's all we could smell during the QC tests
! We used to do rail tickets and bag tags too, great job overall!
