Seposeve 2 Pack Silicone Sippy Cups, Leak-Proof Baby Straw Cup for 6-12 Months, Spill Proof Toddler Cup with Straw 1-3 Years, with Capacity Marking, Non-slip Handle, Flow Control, 6 oz, Green Blue

Premium Food-Grade Silicone: Safe, Durable & Multi-Use Convenience

• Crafted with 100% food-grade silicone, our baby sippy cup prioritizes safety and health for your little one. The ultra-soft, ensuring no worry sipping during every stage of development.
• It effortlessly transitions between environments: microwave breast milk safely, survive daily dishwasher cycles (top rack recommended), or store pre-chilled smoothies in the freezer compartment.

—Easy to clean surface repels juice pigments and milk residues, while the seamless inner walls prevent bacterial buildup in crevices – perfect for parents seeking low-maintenance feeding solutions.

High-Visibility Capacity Markings: Track Every Sip with Precision

• Embedded with bold, laser-etched measurement lines, our cup empowers parents to monitor daily fluid intake effortlessly.
• The ultra-clear, non-fading remains legible even after repeated washing, displaying ounces and milliliters for global convenience. Unlike printed marks that wear off, our scratch-resistant won’t flake into drinks.
• Caregivers can accurately mix formula, track breastmilk volumes, or ensure medication dosing—no guessing required. The raised markings provide tactile feedback for low-light scenarios, while the Bright color design catches the eye during playtime.
• For toddlers, the visual cues act as a fun “water challenge,” encouraging them to finish their drink by reaching the next line.

—Tips: proper hydration supports digestion, cognitive development, and overall wellness.

Spill-Proof 3.0 Straw Technology

• The upgraded anti-leak straw system features a revolutionary “”water after bite” valve that opens only under suction/bite, creating a liquid-lock barrier against gravity and pressure changes.
• Unlike standard straws that drip when tilted, our 5-layer protective design includes:
• 1) A weighted stainless steel ball that always stays submerged
• 2) A collapsible silicone accordion segment absorbing impact
• 3) A directional flow channel preventing backwash
• 4) A quick-response duckbill valve blocking air inflow
• 5) A reinforced bite-resistant tip. During lab simulations mimicking toddler throws (6ft drop onto concrete), the straw retracted fully into its protective housing without liquid ejection.

—The splash-free design proves invaluable during messy milestones – no more juice geysers during car seat or milk fountains at the high chair.

Upgrtade 3.0 Leakproof Cup Seal System

• Even if your baby shakes or tilts the cup, or throws it away, it will not leak, and your baby will enjoy drinking water every day.
• Our patent-pending SeposeveLock mechanism creates an airtight fortress where cup meets lid.
• The dual-layer protection combines medical-grade silicone gaskets with precision-engineered threading that clicks audibly when fully secured.
• We rigorously tested 2,876 open/close cycles and 360-degree rotations at 4.3psi pressure – zero liquid escape observed even when shaken violently or tossed in diaper bags.

—The recessed drinking port features a self-sealing membrane that automatically closes when not in use, preventing accidental spills during car rides or stroller adventures.
