Curated by Sandry Law during a sourcing trip to Shenzhen’s precision district
Sandry Law spotted the prototype for this scale in a cramped workshop near Huaqiangbei, where a third-generation instrument maker was building digital callipers for watch repair. It wasn’t a tea tool yet — just a laboratory balance with an unusually wide stainless-steel platter. Sandry asked if the platform could be enlarged to hold a gaiwan. The maker, Mr. Guo, raised an eyebrow, then spent an afternoon milling a custom silicone mat and rewriting the button logic so a double-tap would start a silent timer. After six months of field testing with the Teamotea procurement team in Kunming — weighing puerh cakes on damp mornings, timing delicate jasmine greens — the final version landed in our catalogue. Every unit is hand-checked by Mr. Guo’s small team, with a signed calibration card tucked inside the box.
