Join the leading jewelers to stock Chrysmela. I HAVE A STORE AND AM INTERESTED IN WHOLESALE. Chrysmela itself will not render earrings or posts hypoallergenic. That may trigger irritation, causing some small children constantly pull on their earrings. We recommend keeping it away from children under the age of three.Īdditionally, while Chrysmela is hypoallergenic, some earrings posts and base are not. Chrysmela is a small item, and a choking hazard.

Also, please watch the helpful video on this website, here. Slide the tip of your fingernail under the very top plate of Chrysmela, unlock it, and then pull it away, as described in the product brochure you received. We recommend to clean Chrysmela every 4-6 weeks, and even more often during the summer months.Ĭhrysmela sometimes locks onto a post so securely that it needs to be “unlocked” before being pulled out of the box, or removed from the earring. Hair conditioners, sunscreen and natural skin oil may accumulate inside and may compromise Chrysmela’s strong hold. Just like eyeglasses or jewelry, Chrysmela needs cleaning periodically.

Earring posts sometimes vary in size, even for the same pair of earrings. More importantly, they can be adjusted slightly for your comfort.

In general, Chrysmela works well on screw posts. Second: if your earring gets caught in your hair or sweater and moves, Chrysmela firmly grips onto the little notch at the end of your earring post - this acts as a safety net. So it may feel “normal” or “nothing special,” but rest assured, they are very secure. HOW SECURE IS IT?Ĭhrysmela holds your earring securely in 2 ways: First: While invisible, 3 micro ball bearings are working hard to hold tight onto the earring posts when your earlobe is “sandwiched” between the earring and the back. But some delicate earlobes and elongated piercings may benefit from the extra support of Chrysmela Extra. Chrysmela Catch is strong and secure enough on its own to hold even your heaviest statement earrings. We introduced Chrysmela Extra for customers who are accustomed to using a disc-type earring back. The only difference is the removable PVC disc that is included in Chrysmela Extra for lift and support. Chrysmela Catch and Chrysmela Extra are identical in terms of mechanism.
