BLUEPOLAR 13 oz Glass Tumbler Set Amber 4-Pack — Double-Wall Insulated, Screw-On Dustproof Lid

BLUEPOLAR's 13 oz double-wall glass tumbler is a four-pack insulated cup with a dustproof screw-on lid and reusable glass straw designed to keep drinks at temperature while protecting hands.

These 13-ounce tumblers combine tempered, thickened glass construction with a double-wall design, a screw-top lid and a glass straw to offer a reusable alternative for everyday cold or warm beverages. The set ships in protective packaging and includes features focused on safety, durability and easy cleaning (lid excepted). This description outlines what the cups do, how to use them, and who benefits most from choosing this amber-colored four-pack.

How does the double-wall design affect temperature and hand comfort?

The double-wall glass creates an insulating air gap that slows heat transfer, helping cold drinks stay cooler and warm drinks retain heat longer without making the outer surface uncomfortable. Because the outside stays closer to room temperature, you can hold a hot beverage without feeling excessive heat on your fingers.

• Double-wall glass for thermal insulation and reduced condensation
• Thickened tempered glass adds strength for hot and cold use
• Outer surface remains comfortable to touch even with warm liquids

What makes this tumbler set durable and safe to use?

BLUEPOLAR uses thicker tempered glass and a glass straw to improve durability and reduce exposure to plastics. All components are free of lead, BPA and BPS; the tumbler body (not the lid) is top-rack dishwasher-safe and should not be microwaved or frozen.

• Tempered, thickened glass resists thermal shock and breakage
• Glass straw included for a plastic-free drinking option
• Lead-free and BPA/BPS-free materials for safer everyday use

How convenient is cleaning, transport protection and everyday use?

The tumbler body fits top-rack dishwashers for straightforward cleaning, while the screw-on dustproof lid prevents spills and keeps debris out. Each four-pack is securely packaged with heavy bubble holders and thick carton protection to reduce transit damage.

• Top-rack dishwasher-safe tumbler body (lid hand-wash recommended)
• Screw-top dustproof lid minimizes spills and contamination
• Protective packaging included to prevent damage during shipping

What are the product dimensions and practical uses?

Each glass measures approximately 4.9 inches tall with a 3.2-inch opening and includes a 6.6-inch glass straw, making it suited to both sit-down and grab-and-go moments. The 13 oz capacity is ideal for coffee, iced tea, infused water and other everyday beverages.

• 13-ounce capacity—compact yet generous for many drinks
• 4.9 in height and 3.2 in mouth width for standard lids and sleeves
• 6.6 in glass straw included for comfortable sipping

Who is this for: The BLUEPOLAR 13 oz tumbler set is aimed at people who prefer reusable glass drinkware over plastic, want a tidy four-pack for home or office, and value insulated glass that keeps beverages comfortable to hold. It suits environmentally conscious buyers who need a compact, attractive amber option for daily coffee, tea, juice or cold drinks and who can follow the care guidelines (no microwave, avoid freezing, lid hand-wash recommended).
