Stamp works welll. I bought an ink bottle in order to refill the stamp, but there is no indication of how to do that.

Reply from Simply Stamps:
I'm glad you love the stamp. Your original ink that came with the stamp should be good for a long time, but when it eventually runs out, all you have to do is pull out the ink pad and use your ink bottle to re-ink the pad, then place it back in.
