Eye Care Products
Our core business. Moisture chamber glasses, hydrating sleep masks, anti-fog safety glasses, side shields, CPAP accessories and swimming goggles. 26 active Amazon SKUs.
From moisture chamber glasses to hydrating sleep masks and CPAP accessories — we develop, mold and manufacture in our own 1,200 m² facility in Shenzhen, and ship worldwide.
Shenzhen Fu Kang Heng Development Co., Ltd. is the company behind the WAHAH brand. We operate our own manufacturing facility of more than 1,200 square meters in Buji, Longgang, Shenzhen, with a team of 36 skilled employees covering R&D, tooling, injection molding, assembly, quality control and export operations.
WAHAH started with functional eye care — moisture chamber glasses, hydrating sleep masks and protective eyewear sold through our Amazon store WAHAH SHOP. Today we run three parallel business lines and supply both our own brand and OEM/private-label customers worldwide.
Because we own the tooling and the production line, we can move from a sketch or a sample to a finished, retail-ready product — including packaging design, barcodes and compliance documentation — without layers of middlemen.
1,200 m² production & assembly site in Shenzhen, not a trading office.

Experience shipping to North America, Europe, Japan and Korea.
Low minimum order quantities for private-label and trial runs.

Put your brand on proven, already-listed designs. Fastest route to market with minimal development cost.
Bulk supply of WAHAH-branded goods, plus sourcing and consolidation for buyers running mixed containers.
