Bioworld Hello Kitty 40 oz Stainless Steel Tumbler — White Printed Squares, Double-Wall Insulated with Flip Straw & Handle

The Bioworld Hello Kitty Character Squares 40 oz stainless steel tumbler is a durable, double-wall insulated drink container decorated with colorful Hello Kitty squares, a flip straw, and a top handle for easy carrying.

This roomy 40-ounce tumbler blends playful Sanrio styling with practical features for all-day hydration. The white stainless steel body is printed with cheerful Hello Kitty images and red bows arranged in vibrant squares, while the double-wall construction helps maintain beverage temperature. A built-in flip straw and a sturdy top handle make sipping and transport simple, and the stainless steel build resists everyday wear. Keep in mind the manufacturer recommends hand washing to preserve the printed design and finish.

How well does this tumbler keep drinks hot or cold?

The tumbler uses double-wall insulation to reduce heat transfer, helping beverages stay closer to their original temperature longer than a single-wall cup. It’s engineered for everyday use whether you prefer iced tea or warm coffee, though extreme temperature retention varies with environment and lid fit.

• Double-wall stainless steel reduces heat exchange
• 40 oz capacity holds large servings for long outings
• Flip straw lid minimizes spills while sipping

Is the design durable and officially licensed?

This is an officially licensed Hello Kitty product produced by Bioworld, so the artwork and character details meet brand standards. The printed squares and red-bow accents are applied to a stainless steel surface that stands up to regular use, though hand washing is advised to extend print life.

• Official Hello Kitty license ensures authentic character art
• Stainless steel construction resists dents and corrosion
• Recommended hand wash to protect the printed finish

How easy is it to carry, sip from, and clean?

The tumbler’s molded top handle provides a secure grip for commuting, gym sessions, or casual outings. The flip straw is convenient for one-handed sipping, and the wide base reduces tipping. For longevity, hand washing prevents damage to the artwork and insulation seals.

• Top handle for comfortable carrying and hooking to bags
• Flip straw for quick, spill-reduced sipping
• Hand wash only to maintain insulation and printed design
