Eventually the rubber seals may wear out or become damaged through misuse. We have conducted over 50 separate tests on the seals. In all our testing each rubber seal continued to function after 5000 cycles. It is important to note, that even if the seals do wear out your JewelPop will not fall out nor is it broken. Simply replace the seal with a new one and you are good to go. Replacement seals are available from all Kameleon retailers.
