Amazon.com : Dreadlock Extensions Dark Brown Wool Double 。This set is about 18 to 22 inches long. (The DreadLocks have been crocheted. double ended.) These dreads are light weight and fluffy. this set is combination of interlocked black dreads and crocheted blonde light brown dreads. interlocked and crochet DreadLocks do not require resealing like other twisted Dreads, so they don\'t require being sealed again. ranging from 1/2 an inch thick to 1/4 of an inch. (some dreads are thin some thick) I used synthetic hair and yaki hair to complete this
