Made of 100% Pure Cotton, this neckband collar is unique. Generations of experience in textiles led to the development of this product. Machine washable. Three different inter linings are used, a harder on on the outside to give it a smooth finish, a very soft one on the inside (the part that touches the skin) to make it ultra comfortable. Center interlining fuses the two sides with structural strength. It is so easy to care for, durable and long lasting. None of the pesky broken plastic to snip at your neck. Sizes from 14 through 19 1/2 inches in 1/2 inch Increments, 20 and 21. Please allow 5-7 business days for processing. Non-returnable.
