BIBS Supreme is an exclusive pacifier in a stylish Danish design. The unique and elegant shield is designed to facilitate optimal passage of air to the sensitive skin baby’s mouth. The nipple is symmetrically shaped to reduce pressure on teeth and jaw. As the nipple is flat and drop-shaped it supports correct jaw development. Since natural rubber latex is a natural material, color variation may occur. Symmetrically shaped nipple for baby’s jaw development. The pacifiers are made of the highest quality and are 100% free from BPA, PVC and phthalates. The shield is made of Polypropylene (PP) which is a light and durable plastic material. Designed and manufactured in Denmark/EU. Complies with the European Standard EN 1400+A2. BIBS Supreme NIGHT GLOW has the same high quality as the original BIBS pacifiers but has a practical glow feature.The glow feature makes it easy for both parents and little ones to find the pacifiers in the dark and accommodates the frustration it can cause for parents to stand in the middle of the night - in total darkness - looking for the pacifier with a crying child.Simply hold the pacifier up to a lamp for 5-10 sec. to activate the effect. The luminescent effect lasts for 8+ hours. Before first use Remember to sterilize the pacifiers when you take them out of the packaging! This is done by putting the pacifiers in plenty of boiling water for 5 minutes. This only applies before first use. Pour boiling water over the pacifiers. Let the pacifiers soak for approx. 5 min. Pick them up and let them dry on a clean towel. This method is gentle, but still gets rid of bacteria without compromising the durability of the pacifier. Pacifiers are not meant to be boiled repeatedly and can be destroyed by continual exposure to high heat. Instead, follow the instructions above.
