16oz Glitter Double Wall AS Plastic Coffee Travel Tumbler

Sparkling Sequin Double-Wall Layer, Trendy High-End Appearance

Vibrant mixed-color confetti sequins are permanently sealed inside the hollow double-wall gap. Every slight shake brings shimmering flowing glitter effects, delivering the same premium aesthetic as classic star-style coffee cups. The fully enclosed interlayer completely avoids sequin leakage, no messy residue inside or outside the cup after long-term use. The bright decorative interior matches all daily outfits, making it a perfect selfie prop for social media sharing. It stands out sharply on retail shelves and attracts young consumers who pursue fashionable, decorative daily drinkware, also suitable as exquisite holiday and party favors.

The separated dual plastic wall forms an air insulation barrier that cuts off temperature transfer efficiently. When filled with hot coffee, hot cocoa or warm fruit tea, the outer surface stays cool to touch to prevent accidental scalding of palms. For iced drinks, bubble tea and cold juice, the hollow layer slows down temperature rise, keeping beverages chilled longer and stopping condensed water from dripping all over hands, bags or car interiors. Unlike single-layer plastic cups, this double-wall design balances heat insulation and lightweight portability without adding excessive bulk to the tumbler.

Premium Food-Grade Transparent AS Plastic, Safe & Sturdy Daily Use

Constructed from high-clarity food-contact AS resin that meets international food safety testing standards. The material is completely odorless, free of harmful BPA and chemical residues, safe for both hot and cold beverage storage. Compared with ordinary disposable plastic cups, AS material features outstanding crack resistance and impact resistance; it resists scratches during daily carrying and accidental bumps in backpacks or car cup slots. The transparent outer wall also fully showcases the glitter inner decoration while maintaining long-term clear visibility without fogging or yellowing after repeated cleaning.

Slim Streamlined Body + Flip Sliding Sip Lid, Leakproof Portable Travel Design

The slender tall silhouette is ergonomically shaped for comfortable single-hand gripping, and its narrow bottom perfectly fits standard car cup holders for road trips and daily driving. The matched flip lid comes with a sliding sealing cover: slide open the small spout for smooth direct sipping without needing straws; slide the cover fully closed to form a tight seal that stops liquid leakage even when the cup tilts upside down or jostles in tote bags and school backpacks. The wide top opening makes daily cleaning effortless, and users can quickly add ice cubes, fruit slices or coffee creamer without messy spills.

Thickened Grooved Anti-Slip Base, Durable Bottom Protection

The bottom of the tumbler is reinforced with a thickened concave groove design, which increases friction with tabletops, car dashboards and outdoor flat surfaces. It effectively prevents the cup from sliding and tipping over when placed on smooth countertops or bumpy vehicle interiors. The thickened base layer also acts as a buffer to shield the cup bottom from scratches, abrasion and minor impact damage when set down hard, extending the overall service life of the tumbler for long-term daily use.
