Reusable Bubble Tea Straws — 12mm Stainless Boba Straws Wholesale

Yes. The straws are made from SUS304 stainless steel — a food-contact grade material — and our production is FDA and LFGB compliant. Test reports are available: contact us and we'll send the certificates.

A slight metallic taste on new straws is normal. It comes from manufacturing residues, not a quality defect. To remove it: 1) soak in warm water with baking soda for 30 minutes and brush inside and out; 2) rinse, then soak in diluted white vinegar water for 20 minutes; 3) boil for 3–5 minutes and let air-dry. If a strong smell remains after cleaning, contact us.

Not with normal use. 304 stainless resists corrosion well — just avoid leaving the straw soaked in vinegar, juice or other acidic drinks for long periods, and let it dry after washing. If you ever spot rust, contact us.

We don't recommend it. Steel conducts heat quickly, so a very hot drink can make the straw hot enough to scald your mouth. Keep drinks at 40 °C (104 °F) or below.

No. The wall is 0.5 mm thick and every tip is polished smooth after cutting, so the edges are rounded and comfortable in normal use.

The 12 mm bore of this straw is made for pearl milk tea and smoothies. We also produce 6 mm and 8 mm straws for juice, milk and water.

Every order ships with dedicated cleaning brushes. Each brush is 23 cm long — slightly longer than the 21.5 cm straw, so it passes from the top straight through to the bottom — and its 15 mm head is deliberately a touch wider than the 12 mm bore, so the bristles press firmly against the inner wall and scrub it thoroughly. See our straw cleaning brushes for sizes and bulk pricing.
