BloomMark One-Handed Large Capacity Insulated Tumbler – The Future of Convenient Hydration
Meet the tumbler that redefines convenience. The BloomMark 1100ml Insulated Tumbler is engineered for those who need maximum hydration without the hassle of constant refills. With a patented one-handed, one-touch open/close mechanism, you can sip effortlessly while driving, working, or working out—truly hands-free hydration.
Premium Materials for Pure Taste & Safety
316L Food-Grade Stainless Steel Interior: Unlike standard 304 stainless steel, our 316L interior offers superior corrosion resistance, making it ideal for acidic drinks like coffee, juice, and cola. It resists pitting, staining, and retains no metallic aftertaste.
Tritan One-Piece Lid & 9mm Thick Straw: The transparent Tritan lid is BPA-free, heat-resistant, and odor-resistant. The 9mm-wide straw is smooth, durable, and won’t absorb lipstick, ensuring a clean, comfortable sip every time.
Powerful Temperature Retention
6-Hour Cold Retention (< 6°C / 43°F)
6-Hour Hot Retention (> 55°C / 131°F)
6-Layer Locking Material & 3mm Thick Lid: Our advanced vacuum insulation, enhanced by a 3mm thickened lid, boosts thermal performance by 30%, far exceeding national standards.
Innovative Leakproof & Venting Design
Patented One-Handed Operation: Push the yellow button with your thumb to hear a satisfying “Ka-da” click—the lid pops open instantly. Push it again to seal automatically.
First-Ever Valve Structure for Straw Lids: This vertical-pressure sealing mechanism prevents internal pressure buildup, eliminating the risk of hot liquid spraying or leaking when you open the lid.
100% Leakproof: Toss it in your bag or leave it on your car seat—no spills, no worries.
