Promising review: This pen is amazing! My fianc is not a huge jewelry person so I was not thrilled when he proposed to me. However, I was afraid of having to take such a gorgeous ring in for cleaning and care. When I saw this pen, I thought it was $5. It seemed easy enough! It was so good that I took photos before I used it. It took me four seconds to put it on and I was amazed at how easy it worked. It is a great product and I plan to buy it again. I also bought many more for family members as gifts. This is the perfect item for people like myself who don't care about jewelry. It's amazing. It's an amazing product. It works almost like magic. These photos were taken a few days later than the last cleaning, and then right after. Yet, it is a big difference! ImogeneAmazon has it for only $6.58
