Is one allowed to remove (by tearing) a cleaners' tag from his/her shirt on Shabbos?
In the Shabbos Home it brings Reb Moshe Feinstein allowed going out with tags attached by Staples on Shabbos as it is Mevutal(SECONDARY?) to the clothing if one forgot to remove it before Shabbos. Based on Conjecture I am guessing removal would not be allowed according to him. although Reb Simcha Bunim Cohem In the Shabbos Home Volume 2 allows removing the Price Tags.
