Frequently Asked Questions

We offer domestic shipping to Singapore. All products are stocked in Singapore and are delivered within 3-5 business days.

Answer richtext

Yes! Thanks to our double-wall vacuum insulation, it keeps drinks cold for 24 hours and hot for 12. We’ve tested it ourselves—and made sure it performs better than most tumblers out there. Just make sure the lid is fully sealed!

Absolutely. Our tumbler is dual-temp engineered to handle piping hot coffee (up to 12 hours) and icy cold water (for 30+ hours). Unlike other brands, we don't hide fine print—you can safely enjoy both without compromising performance.

BriteLune tumblers feature a dual-locking mechanism that’s been drop-tested (yes, even on carpet!). Flip top lid is 100% leakproof, perfect for your bags. And even when you are using straw, the spill resistant-seal holds strong.

Never. BriteLune is made with premium food-grade 18/8 stainless steel—non-toxic, BPA-free, and rust-resistant. Plus, we coat the interior with a non-reactive finish so your drink stays pure, odor-free, and great-tasting all day.
