An elastic wrist strap band is about 3.5cm wide and they can be found of different lengths say from about 12cm to 25cm and in colours (JewelTM), it has a square part where the connection to a grounding cord is made, these upper and lower square parts snap together over the fabric as to produce a joint. In the centre of this square we find a stainless steel (perhaps machined) snap stud (found on a few standard sizes) to allow for a wrist strap cord snap-on connection. This square part is of a dissipating material in the outer part and of stainless steel on the inside, for better contact to the skin. The strap band itself is also of a ESD dissipating material on the outside but carries conductive fibres interwoven with the fabric in the inside as to facilitate conductivity, these fibres do not touch the outer material. These elastic band can also be found adjustable, this is similar in manufacturing to the above strap, however has a stainless steel cam locking mechanism on top of the squ
