  • PREMIUM MATERIALS FOR SAFETY & LONG-LASTING USE – Toddler cups spill proof make of high-quality 304 stainless steel paired with soft, food-grade silicone, free from BPA, lead, and phthalates. The stainless steel sippy cup resists dents and heat while the silicone straw and rim protect delicate gums and teeth. Ideal for little hands and tough enough to handle every drop or tumble, ensuring years of reliable use through your baby’s growth.
  • LARGER 8 OZ CAPACITY THAT GROWS WITH YOUR CHILD – Toddler sippy cups thoughtfully sized at 8 oz (250 ml), holding more than standard 7 oz cups, giving parents fewer refills and toddlers more independence. Perfect for water, milk, or smoothies — large enough for outings but still light for small hands. One cup accompanies your child from early sips at 6 months to confident drinking at 3 years.
  • COMPLETE VALUE SET FOR PARENTS & GIFTING – Straw cups for toddlers 1-3 comes with everything you need: a replacement silicone straw, a cleaning brush, a portable dust cover, and a premium gift box. Every detail is designed for real-life parenting — easy to clean, ready to travel, and beautifully packaged for baby showers or birthdays. A practical, thoughtful choice that saves time and adds delight.
  • LEAK-PROOF, EASY-CLEAN STRUCTURE FOR STRESS-FREE USE – A precision-sealed design and wide-mouth construction make cleaning effortless while keeping leaks under control. All parts detach for thorough washing and are safe for the top rack of the dishwasher. No trapped residue, no hidden mold — just a clean, worry-free cup that makes daily routines simpler and happier.
