DexasMini Silicone Oven Mitt with Raised Nibs, Red

what is the difference in the mini mits

Is this a set of two mitts or just one?

Is this a set of two mitts (like at BedBathBeyond)?

This may seem a daft question, but has anyone tried this as a makeup brush cleaner (like the Sigma glove)? If so, can you please share how it worked?
