WINSA 46 oz Glass Tumbler with Bamboo Lid & Two Straws — Black, Ergonomic Handle

WINSA's 46 oz glass tumbler is a large travel-ready drinking cup with a natural bamboo lid, two reusable straws, an ergonomic handle, and a silicone sleeve designed to sit securely in most car cup holders.

This roomy WINSA glass tumbler blends a durable, thick glass body with a natural bamboo lid wrapped in a silicone sleeve, offering a clean, sustainable alternative to single-use cups. At 46 ounces it holds generous portions of iced coffee, smoothies, bubble tea, or water, while features like the capacity marker, dishwasher-safe construction, and two straw styles make everyday use and hydration tracking simple. The black finish and practical handle keep the design both modern and functional for home, office, and travel.

How does this tumbler behave in a car or when commuting?

The WINSA 46 oz tumbler is shaped and sized with common car cup holders in mind, so it fits securely in most vehicle consoles. The silicone sleeve around the bamboo lid helps reduce slips and shields the wood from moisture while the handle offers an extra grip point when moving between car and desk.

• Profiles to fit standard cup-holder diameters
• Silicone-wrapped lid resists slipping and keeps wood dry
• Ergonomic handle for stable one-handed carrying

What drinking options and accessories are included?

This set includes a natural bamboo lid plus two removable straws — a wide pearl straw and a slimmer straw — so you can switch between thick shakes or bubble tea and thin beverages like iced coffee. The removable straws make it easier to clean and the lid’s silicone sleeve prevents direct contact with the wood surface.

• Pearl straw for bubbles and thick smoothies
• Slim straw for water, tea, and coffee
• Removable straws for straightforward cleaning

Is the glass durable and easy to clean?

WINSA uses thickened glass for everyday resistance and places a food-grade silicone sleeve around the cup for extra protection and identification. The glass body and silicone sleeve are dishwasher safe, and the capacity marker printed on the side helps you measure intake without extra tools.

• Thickened glass construction for routine use
• Dishwasher-safe glass and silicone components for easy cleaning
• Capacity marker for simple hydration tracking

How does the handle and design improve comfort and safety?

The ergonomically shaped handle keeps your hand away from hot or cold surfaces so you can hold the tumbler comfortably without temperature discomfort. The handle also reduces the chance of accidental drops and gives better control when walking or driving with your drink.

• Ergonomic handle for comfortable gripping
• Less slipping thanks to the silicone sleeve and handle contour
• Stable weight distribution even when full (46 oz capacity)

Who is this for: The WINSA 46 oz glass tumbler is aimed at people who want a large, reusable cup for long outings, commutes, or active workdays—especially those who drink bubble tea, smoothies, or large iced beverages. It suits commuters who need a cup-holder-friendly shape, home users who want a dishwasher-safe glass with a natural finish, and gift buyers looking for a practical, well-designed tumbler for friends and family.
