Quite well! The material we use has a starting break point of several hundred pounds per square inch, even for the thin, skinny straps. The thicker pieces can rate over a thousand pounds. All our straps are easy to clean and sterilize with alcohol or soap and warm water. They are also impervious to oils. Some of the finishes are hard and shiny, while others are matte and soft. Please let us know if you have a preference.
