You may wish to purchase these if you need a replacement or would like a different colour strap.
The straps are available in Black, White, Red, Blue, Brown and Peach and in 3 different lengths.
To find the length you need measure the circumference of your arm. If you don't have a fabric
measuring tape then you can wrap a piece of string around your arm mark it and measure that.
The length of elastic matches the maximum circumference of the arm. For example for a 35cm
arm the 40cm strap would be needed. If you find you have a lot of excess strap after you have
adjusted it you can cut the excess off and seal the edge with flame.
The elastic arm strap may contain latex.
