Review on 3-Piece Set of Durable Stainless Steel Funnels for Transferring Essential Oils, Liquids, and Dry Ingredients – Mini Filling Kitchen Funnel Kit with Large to Small Sizes, Dishwasher Safe by Adam Radford

I bought this to pour hot water into my glass bottles. I didn't want to use a plastic funnel because the plastic funnel didn't say "no BPA" exactly. So I got this metal funnel for it. That worked wonderfully at first. However, after a few weeks I noticed a very slight rust color on the pins that attach the handle to the funnel itself. I rubbed vigorously with a wire brush and now I can barely see the rust staining. I took off 3 stars because I don't think food grade stainless steel should have this type of metal rust.
