The Cubkins Temp-Sensing Breast Milk Storage Bags are designed for pumping mothers who want convenience and confidence in every feed. Fill from the top, store flat in the freezer or upright in the refrigerator, and let the built-in temperature indicator show any caregiver when the milk has reached feeding temperature — Purple means cold (below 36°C), Blue means ready to feed (36–40°C), White means too hot (above 40°C). No thermometer, no guesswork. Every bag is pre-sterilized using gamma sterilization and stays sealed until you open it — no washing, no boiling, ready straight from the box. The one-way design fills through the wide top zipper and pours through a separate tear-away side spout, so milk never passes the surface your fingers touched. The reinforced dual-track zipper is designed to keep milk securely in the bag through freezing, thawing and transport, and the 250 ml capacity holds 25–40% more than typical 180–200 ml bags — fewer bags on high-supply days. To warm milk, stand or swirl the sealed bag in warm (never boiling) water and let the indicator colour settle. Do not microwave, do not boil, and never refreeze thawed milk. Bags are single use only. Storage guidance: use within 4 hours at room temperature (25°C or cooler), up to 4 days in the refrigerator, and up to 6 months in the freezer for best quality (up to 12 months is acceptable). Once thawed, use within 24 hours. Made from BPA-free, BPS-free, phthalate-free, food-grade PE & PET film. Each box contains 25 pre-sterilized 250 ml bags and 1 dual-tip marker (ballpoint + permanent). Designed in India, for Indian families, by Cubkins — little people things.
