Frezonika 4 Pcs Silicone Koala Sleeves for Dr. Brown Narrow Glass Bottles - 8 oz, Pink

A Thoughtful Sleeve for Narrow-Glass Bottles

Frezonika offers a 4-pack of silicone koala sleeves designed to fit Dr. Brown Natural Flow narrow-neck glass bottles in 4 oz and 8 oz sizes. The pink set pairs cute design with practical features, including loop handles that help little hands grip the bottle with confidence. Note: these sleeves are tailored for the narrow-neck bottles and are not compatible with wide-neck models.

What you can expect

• Custom fit for Dr. Brown narrow-neck glass bottles (4 oz, 8 oz), keeping the bottle shape intact.
• Soft silicone that helps retain warmth, potentially keeping milk at a comfortable temperature during feeding.
• Reinforced 5 mm base adds a cushion against bumps and drops, supporting everyday handling.
• Cute koala silhouette with built-in loop handles encouraging early independence and easier grip for small hands.
• Visible milk level through side cutouts, so you can check volume at a glance without removing the sleeve.
• Dishwasher-safe, BPA-free material designed for easy cleaning after meals.

Real-life moments

In busy mornings or fussy evenings, a warm, grippable bottle can make feeding calmer. The koala sleeve offers tactile feedback for tiny fingers and may help a caregiver position the bottle more securely. The clear milk window supports quick checks without interrupting a feeding rhythm.

• Potential help for slow feeders by maintaining a comfortable temperature while feeding pace varies.
• Built-in handles supporting independent bottle holding as little ones practice grip and coordination.
• Simple monitoring of milk volume during mid-meal pauses.

Care, safety, and what is included

Made from BPA-free silicone, these sleeves are dishwasher-safe for straightforward cleaning. They’re designed to accompany your Dr. Brown bottles, not to replace bottle guidance. The pack contains four pink koala sleeves ready to pair with your existing set.
