We are a small family owned and operated business catering to long range competitive rifle shooters. My son, Greg, has designed a new style of competitive rifle sling and has decided to use a Bio-thane material for its construction, before we place a substantial order for materials we would like to request some samples, as listed below
20 feet of 1.5" Beta520 color#BR523 and 
12 feet of 2.0" Beta520 color#BR523

Thank you for your time
