Notdam Heart Gua Sha

The Notdam is engraved in a stylish font. When I first received it, it had a strong metallic smell like coins, so I soaked it in vinegar water for about an hour and then washed it, which helped a bit. As expected of a brass product, it has a substantial weight and thickness. I feel that the weight makes the massage more effective, even when massaging gently by scraping. It seems to be effective for my double chin, but I was most satisfied with its effectiveness on leg and foot swelling.
