I wasn't sure about the size and length since I don't have a ruler or tape measure at home, but all the reviews were really good, so I rolled the dice. Boy am I glad that I did! These are perfect-the length and the size is just right and the shape is also perfect-they look round, which is what I wanted. The clasp is different, it's a ball and you have to press down on the lever to release the clasp, but then you slide it back into the silver ball and it's hidden. Very unique and clever. All in all, great purchase-price and quality exceeded my expectations!
