kayearthgrown Posted September 5, 2008 Share Posted September 5, 2008 I just ordered the 1-1/2 oz portion cups that are suppose to be made with polypro (stated on the website) but they have a 6 on the bottom. Do all polypro have a 5 on the bottom? TIA Quote Link to comment Share on other sites More sharing options...
Camay Posted September 5, 2008 Share Posted September 5, 2008 Polypropylene = 5Polystyrene = 6Looks like their website is wrong, or they shipped you the wrong item. I would contact them. Quote Link to comment Share on other sites More sharing options...
