Nylon Reins have a black rubber-grip coating at the hand.  Dirt and sweat can work their way into the nylon fabric, so it is important to keep them clean, either by hand washing or machine wash (gentle cycle).  Special Order colors available in Navy Blue, Hunter Green, Lime Green,  Red, Hot Pink, Purple, Yellow and White.  Sorry but Royal Blue is no longer available.  ALLOW 3 TO 4 WEEKS FOR DELIVERY.  All sales for colored reins are final.  If you want the option for a 30 day trial, purchase black or brown reins.  You will then have the option to trade these in for colored reins within 60 days of purchase.
