*Please Note - The photo etched stainless steel portion is over molded with polypropylene (plastic). When the piece is removed from the injection molding machine, the polypropylene cools and shrinks slightly while the stainless steel does not. This shrinkage causes the stainless steel to wrinkle, but it will not affect the functionality of the permanent filter.
