The grip material of Versa Gripps was developed over a 3-year period, and it is manufactured in the USA under a proprietary agreement. Due to the unique production process of this material, there may appear some distressed areas or irregularities. These marks are caused by the curing process of the material and will not affect the performance of the product. In addition, the natural rubber foam of the wrist wrap may show small bubbles or holes on its sides. These are a naturally occurring effect of the curing process of the rubber and will not affect the performance of the wrist wrap portion.
