Product Code: BT-GS-04 · Model: SGS103
Model SGS103 — an angel-wing gua sha board whose double-curve body mirrors the natural lines of the face and neck. One wing edge fits the cheekbone and jawline, the other sweeps the neck and shoulder; the tapered comb profile at the tip stimulates the scalp and meridian points. High-precision grinding and hand polishing produce a smooth mirror finish that glides cleanly with serum, and the solid 304 steel body gives a comfortable, pressure-carrying heft. Rust-free, easy to sanitise, and built for years of daily use.
All metal parts are produced in-house: stamping/progressive dies, CNC engraving, hand polishing and a 3-stage QC line. Face-contact items use food-grade 304/316L stainless steel with REACH-compliant finishes; gift items offer zinc alloy with plating thickness tested by salt-spray. Material certificates for the actual production batch are available on request — see Manufacturing for the full process.
