【Robust Protective Shield】 – The sturdy silicone sleeve significantly reduces the impact force when a glass baby bottle falls to the ground, thereby providing a robust protective shield and preventing the bottle from breaking.
【Convenient for New Parents】 – The LOTBILL silicone baby bottle sleeve is made of premium food-grade silicone material, capable of withstanding stretching and twisting during use. It also facilitates quick sliding of the bottle. The window design allows you to see the milk and feeding scale at any time without removing it. It is safe for dishwashers and sterilization.
【Care for Babies and Parents】 – The silicone sleeve has an anti-slip effect, making it easy for both babies and parents to grasp. The soft material is gentle on both the baby’s small hands and the parent’s fingers. The texture and softness of the silicone sleeve can help them develop a better grip.
【Good Insulation Effect】 – The silicone baby bottle sleeve can keep the bottle’s liquid temperature and maintain its temperature longer than a sleeveless bottle.
【Perfect Fit】 – This baby bottle sleeve is specifically designed for Dr. Brown’s Natural Flow Options+ Glass Wide Neck Bottles in 4 and 5 oz (Not applicable to other series)

These silicon sleeves fit the Dr. brown wide neck glass bottles perfectly, with openings to still be able to read the bottle measurements. They are more affordable than the brand name sleeves, but are slightly thinner. They are still so useful in adding some grip and protection against breakage to the glass bottles! Easy to clean and to use.
Great fit on the bottles. Will be very helpful in protecting the glass bottles! The silicone has a thick bottom so it will with accidental falls.
