Everything in the cleaning pack is made without BPA for peace of mind. The storage case is made of food-grade ABS plastic; the silicone brush heads are food-grade silicone; the small brush is food-grade and made from nylon, stainless steel, and silicone; and the brush handles, soap dispenser, and drying rack are made from food-grade plastic.

Yes! All pack components (except for the soap dispenser) are dishwasher safe. For best results, use the normal cycle.

Sometimes these plant-based cleaning agents don’t like rapid temperature differences and turn a cloudy or off-color en route to retail stores or your house. This is a cosmetic issue only: they are still safe and effective. It usually clears when the bottle warms back up, but if yours doesn’t, simply soak your bottle or refill pack in warm water for 15 minutes and it should look as good as new.

The Willow Portable Breast Milk Cooler holds up to 16 ounces of breastmilk. (That's 3-4 pumping sessions' worth of milk on average.)

You can put the stainless steel Cooler vessel and the Lid with Handle into the dishwasher. We recommend hand-washing the Ice Pack.

For optimal results, put ice pack in freezer for at least 8 hours, and ideally up to 12 hours.

Travel Cleaning Pack: 7.9” x 7.5” x 1.8” when closed. Small bristle brush is 5.8”. Medium silicone brush is 5.6”. Large silicone brush is 9.8”. Soap dispenser is 5.8”.

We understand that safety is your top priority. It's ours, too — and we are committed to only selling products that keep babies and breast milk safe.

Like many cooler products on the market, our Portable Breast Milk Cooler was made with a standard vacuum insulation process, utilizing mixed metals that may contain lead at a point on the bottom exterior of the cooler. This point is securely covered and is designed to be completely inaccessible to any liquid or person using the product. Only purposeful misuse or intentional damage to the Portable Breast Milk Cooler could make it accessible.

Every surface of the Willow Portable Breast Milk Cooler that comes into contact with liquid or skin meets all required federal food-grade and safety standards, and the Consumer Product Safety Improvement Act (CPSIA). Additionally, Willow Portable Breast Milk Cooler also meets the European Union’s REACH and RoHS standards, and BPA/BPS, PFOS, and phthalate safety standards.
