Key Features

Small to Carry, Big on Style: The Macaron Slim Series
Value Prop: In a market dominated by bulky oversized bottles, our Macaron Slim Series stands out by being compact and chic. Designed specifically for the modern commuter and lifestyle enthusiast, it fits effortlessly into small handbags and car cup holders, ensuring your morning brew stays at the peak temperature for up to 12 hours.
B2B Edge: A high-turnover item for boutique retail and coffee shop merchandise, offering the perfect blend of fashion aesthetics and industrial-grade insulation.

Premium 18/8 Stainless Steel & Skin-Feel Texture
Tech Detail: Every tumbler is crafted from food-grade SUS304 (18/8) Stainless Steel, ensuring zero metallic aftertaste and high corrosion resistance. We use an advanced powder coating process to create a velvety "Scrub" finish that provides a warm, non-slip grip.
Insulation: The double-wall vacuum barrier effectively prevents external condensation (the "no-sweat" effect) while locking in heat for 6 hours.

Versatile 2-in-1 Dual-Drinking Innovation
Innovation: Why choose between a straw and a spout? Our patented Dual-Sip Lid offers both. Use the food-grade silicone straw for safe, no-tilt sipping while driving, or flip the tab for a wide opening to enjoy hot coffee.
Safety: Features a triple-sealing silicone ring system, providing a 100% leak-proof guarantee when thrown into a bag or backpack.

The Perfect Canvas for Your Brand Identity
Customization: The clean, straight body is an ideal canvas for branding. We offer precision factory-direct services including 360° Cylindrical Printing, Laser Engraving, and 3D UV decals. Custom Pantone color matching is available for our curated pastel palette.
Retail Ready: Supplied in high-quality neutral English gift boxes. We support low MOQ stock orders to help retail brands scale efficiently with retail-ready packaging.

Frequently Asked Questions
Why is 18/8 stainless steel better for a slim pocket tumbler?
18/8 (SUS304) is the food-grade standard that contains 18% chromium and 8% nickel. This ensures the tumbler is highly resistant to rust and corrosion while maintaining a pure taste without metallic odors. For a compact "pocket" bottle, this durability ensures a longer product lifespan and safe daily reuse.
Is the Gencore dual-sip lid truly leak-proof for bag carrying?
Yes. Our lid is engineered with a high-tension snap-lock and a medical-grade silicone sealing system. Once the flip tab is clicked shut, it creates a 100% airtight seal. You can toss it into your handbag or lunch tote with total peace of mind.
Can I customize the colors for a small batch order?
We keep our 6 core Macaron colors in stock for low MOQs starting at 50 pieces. For custom Pantone colors or full-wrap private label designs, the MOQ starts at 500-1000 pieces, allowing you to create a unique product line for your brand.
What certifications do Gencore slim tumblers carry for global import?
All Gencore drinkware products undergo rigorous third-party testing to meet global safety standards. Our Macaron series is fully certified with FDA, EC, LFGB, and BPA-Free standards, ensuring safe market entry in North America and Europe.
