Bracelets:
To keep your bracelets looking as new as possible for as long as possible, I suggest avoiding getting them wet. Be sure to wash your hands carefully and take them off before bathing and swimming. I also suggest rolling bracelets onto your wrist instead of stretching them over your hand; this can help preserve the elastic/stretchiness of your bracelet.
Wax Seal Necklaces:
To keep your necklaces in good shape, I once again suggest not letting them get wet. Please do not bathe or swim with them on, this could ruin the wax. I also suggest avoiding wearing them when it's hot outside, as they are made out of wax and have the potential to melt.
