I'm new to making bottle stoppers and saw where nilesbottlestoppers.com was recommended by a few of you. I found another site that was cheaper and ordered stoppers from them: stainlessbottlestoppers.com My neighbor is a machinist and said I did not get food grade stainless as advertised. He put a magnet on the stoppers and said it would not stick to 304 grade stainless steel.
My question is; does it really matter what grade they really are? I like their prices but don't want returns from my customers.
