Pigeon Nipple Brush - 1 brush only. This brush thoroughly cleans the inside of the nipple. A dedicated brush perfectly shaped for slim-type nipples. It cleans the fine grooves on the back of the nipple. The fine-grained urethane sponge won't damage delicate nipples. It has an easy-to-grip stick shape and a hook hole for hygienic storage. 〈Nipple Care〉 ● After feeding, immediately soak in lukewarm water and wash carefully with Pigeon bottle wash, etc. Insufficient cleaning can cause odors and stickiness. ● Nipples are delicate. Especially the suction hole area has thin rubber, so there is a risk of tearing. When washing the nipple, wash while holding the tip of the nipple with the pads of your fingers. ● Gently wash the air vent and suction hole with both hands. Washing too hard or pulling can tear the valve and cause leaks. 〈Precautions for Use〉 ● Replacement guideline: Approximately 1 month * Brushes are consumables. Replace with a new one when wear and tear or dirt become noticeable. ● Pressing the sponge too hard against the nipple, twisting, or pulling can cause tearing or ripping. ● After use, be sure to rinse off the detergent thoroughly, drain the water, and dry away from direct sunlight. ● Boiling, microwave, and chemical disinfection are not possible.
