Care
Your beads are pretty low maintenance, they won't break or scratch easily so run wild while wearing them. But please please please do not wear them into the shower! Bodhi beads cannot get wet (they might seed into a tree, who knows).
As far as oiling goes, you can use anything, really. Your natural oils from your hands will do just fine, but in case you want an extra bit of shine faster, you can just use any animal or plant based oil, like baby oil or coconut oil. However, they will take on the smell of whatever oil you use, so choose wisely or your beads may end up smelling like pizza.
