Warehouse & Fulfillment Centers

Primary Warehouse Location:

📍 2783 Teagarden St, San Leandro, CA 94577
🔹 No walk-ins – Please call first.

Global Manufacturing & Distribution

🌏 Our manufacturing facility is based in Mainland China, and we partner with a network of third-party warehouses worldwide.

This enables:
✅ Faster shipping times
✅ Lower prices for our customers
✅ Optimized inventory management

📦 Shipping & Order Fulfillment:

We strive to keep stock in multiple locations and always ship same or next day.
Our average shipping time is 2.4 days, though free shipping may take 2-5 business days.
Since we utilize multiple warehouses, orders may ship separately and we cannot guarantee a specific shipping location.
Will Call pickup is available in California only.

📌 Returns & RMAs:
We do not list warehouse addresses as walk-in visits are not available. Returns must have a Return Merchandise Authorization (RMA).
