Review on 📏 Essential Ring Mandrel Sizer Set - 27-Piece Metal Ring Sizer Gauge for Accurate Finger Sizing - Jewelry Tool Kit by Kim Sanchez

I have several sterling silver rings that are a bit small and I stretched them slightly to the right size. You can't go from size 5 to size 10, but you can easily go 1.5 sizes depending on the thickness of the strap. Of course, you should leave expensive engagement rings or love rings to the professionals. This is perfect for cheaper trendy sterling silver rings that are too tight after a few quid but aren't worth the jeweler's time. Best suited for sterling silver or gold rings. Never use it on plated metal and cast metal may not expand.
