The length of this necklace is about 40cm-42cm, Princess style. Toggle clasp is attached at the each end of chains, so you don't need to get findings by yourself. However, Cotton is not included in this product. And you must complete this necklace by putting cotton into each ROSE parts by yourself. And I hope you could enjoy this process........to choose color of the product, and get some colorful wool cotton for Needle Felting from craft shops, handmade material shop, or even drug stores to get simple white or color cotton ball for cosmetic. Making is quite easy and simple. Please just take a proper amount of cotton, and make it round by your hand or roll up by your finger. Then, gently push into the bigger space of each Rose parts. Please not be picky to make cotton round, you don't have to make a perfect round ball. And you don't need to use a tons of cotton, just take a small amount. The cotton would swell out inside of Roses. If you want to change the cotton color, just slowly drug it out of Rose parts, then choose other color. This is easy and fun part. And, of course, you could use this necklace without any cotton, too. It also looks good. Because of shape and design, this product is only available for plastic, not suitable for metal materials. Please check other versions of Rose series Necklace Ⅱ or, also other cotton series would be comimg up soon.
