Have you heard of one? Well, I stumbled upon this website this morning when i was looking out for some remote control toys. I got puzzled on what it is so i checked it out. rock tumblers is a rock container for hobbyists. One popular hobby now is rock collecting and polishing. This site offers the greatest inventory of this item , including rock polishers to go with it. They also offer a very competitive price in the market. I have shared this website to Gelo and he is thinking of giving this hobby a try. Well, that can go with photography right?
