Uncompromising quality is our top priority. Our stainless steel tumblers are engineered with advanced double wall vacuum insulation to ensure maximum heat and cold retention. All products are crafted from premium food grade stainless steel, strictly complying with international FDA and LFGB safety standards. We fully support independent third-party testing to provide valid certification for your commercial orders.

Time is money. Regular customized samples are delivered within 3 working days.

Cost Policy: The fee depends on complexity (e.g., laser logo vs. new mold). However, sample fees or mold opening fees are refundable when your subsequent bulk order reaches the agreed quantity. This makes testing our tumblers in bulk risk-free.

Thanks to our integrated supply chain and semi-finished inventory, regular tumblers wholesale orders can be dispatched within 10 days. Our standardized production lines bypass the initial raw material procurement phase for standard models, ensuring we meet your deadline without compromising quality.

We believe in growing with our partners. The MOQ for regular stainless steel cups is flexible. While we specialize in large-scale production, we accept small-batch customized orders to help you test the market. Please contact our sales team for a specific MOQ plan tailored to your chosen customization process.
