Frezonika Koala Silicone Sleeve for Dr. Brown Narrow Glass Bottles (4 oz) – 2-Pack

Meet Frezonika's 2-pack Koala Silicone Sleeves, engineered to fit Dr. Brown Natural Flow narrow-neck glass bottles in 4 oz and 8 oz sizes. The soft, squeezable silicone wraps around the bottle, creating a gentle grip and a cozy base that little hands can explore during feeding time. Note: these sleeves are designed for narrow-neck bottles and are not compatible with wide-neck models.

From the moment you slip one on, you may notice the sleeve adds a touch of warmth. The silicone acts as a light insulator, helping keep milk warm a bit longer during distracted or fussy moments. Caregivers using slow flow or paced feeding might appreciate the extra buffer of time between checks and sips, while busy households can enjoy a smoother, more manageable feeding routine.

Durability is built in with a reinforced 5 mm base that cushions minor bumps and accidental drops. This extra heft is designed to help shield glass bottles from surface impacts, giving you peace of mind during meals on the go, at the kitchen counter, or in a crowded daycare setting.

Playful design meets practical function

• 🐨 Koala-inspired design adds a playful touch and makes bottles easier for little hands to hold, encouraging independence during feeds.
• 👀 Side cutouts enable quick milk-level checks without removing the sleeve, keeping feeding flow simple and tidy.
• 🧼 Dishwasher-safe and BPA-free for everyday cleaning and reliable safety.

Real-life use and care tips

• Compatible with Dr. Brown narrow-neck bottles in both 4 oz and 8 oz sizes, offering flexibility across feeding setups.
• Rinse after use and place in the dishwasher when possible; allow to air-dry to maintain silicone pliability.
• Inspect the sleeve regularly to ensure a snug fit around the bottle and intact base protection.

In real-life moments, these koala sleeves bring a touch of whimsy to feeding while delivering practical benefits: grip, warmth retention, and quick visual checks. The two-beige sleeves arrive as a convenient set, ready to enhance your Dr. Brown bottles without adding bulk to your routine.
