Nothing really new to add beyond the fact that my stones are both still as nice as they were when I got them. I expected to have to oil their surface to reshine them by now but they're holding up well

I did yank the strings out, however. While they are useful for adding weight, I just don't see myself personally standing around with bags of weights hanging from my vagina and the stones are much more comfy without the strings to irritate my labia! To remove, I just bear down a bit and they slide out easily.
