I appreciate the aspect of it which leads to less packaging waste, but I agree that I don't think it adds to the soap itself.I must be the oddball here, but I really don't like the look of this. I can see using it as a surface design feature of the soap, but I don't care for the 'label' look.
Good point. It's hard to contact the seller if you don't eve have the option to save the label, although IF the consumer wanted to they could photograph the 'label' prior to use, but I don't think that's a reasonable justification for not having a printed label.It goes to traceability and incident reporting. Most labeling the FDA deals with is able to be saved if the consumer wishes or needs to. Hence the question what the FDA would think.
I believe it depends completely on where it is being sold. In a physical store, where the owner is purchasing wholesale from the maker, handing out a card for every purchase is an unreliable expectation. In a Farmer's Market (Fair, or private booths) type setting or when selling online, where the maker is the seller, of course that would work. But that also depends on the regulations of the country/region where the soap is being sold. If the regs require full specific packaging for certain sizes of products, then handing out a card may not meet those requirements. Example: We (USA) have type-size (for printed labels & ingredients lists) requirements that can be included for small sized products, where an extra page or insert or attachment is allowed for cosmetics or drugs. Not all soaps in the US are deemed cosmetics or drugs, but some are. How many differences are there for other countries? I don't even know, but there are many.Encode the contact information into a QR code modelled into the soap bar via soap dough!
On a serious note, this issue arises in any situation where soaps are sold open/unwrapped. Idk, is it a thing to give away a business card with address and/or ingredients along with the soap? Then every customer could decide by themselves if they want to produce a piece of cardboard waste with each purchase, or not.
