Client Reviews

Trusted by Buyers Around the World

What our wholesale and OEM clients say after working with Watersy.

Watersy delivered 5,000 custom tumblers for our outdoor brand in just 28 days. The quality matched the pre-production sample exactly — zero defects. Will definitely reorder.

We've sourced drinkware from multiple Chinese factories. Watersy stands out for their LFGB certification readiness and their proactive communication throughout production. Very professional.

The ODM process was smooth from start to finish. Our 3D drawings were turned into a sample within 12 days. The powder coat finish quality is excellent — exactly what our retail clients expect.

Watersy's local warehouse in Brazil saves us significant import time. We can replenish stock in 7 days instead of 60. That's a game-changer for our e-commerce operation.

I requested FDA and LFGB test reports before placing our first order. Watersy had everything ready within 24 hours. That level of transparency is rare and built our trust immediately.
