An elastic cuff is a flexible band made from elastic material, designed to fit snugly around the wrist, ankle, or other body parts. It is commonly used in clothing, such as sleeves or pant legs, to keep them in place and prevent them from sliding down. Elastic cuffs provide comfort and ease of movement while maintaining a secure fit. In addition to clothing, elastic cuffs are also found in medical applications, such as blood pressure monitors. These cuffs can expand and contract, allowing for accurate measurements. Overall, elastic cuffs are versatile components that enhance both functionality and comfort in various products.
