Super thin Dynamic Rope

I am looking for some thin dynamic rope ( under 6.5mm) ,Edelrid has a 6mm dynamic rap line witch would be perfect but you have to buy a full rope and I'm only looking for 10m , does anyone know of any others out there ?? 

Beal makes a couple of accessory cords that are dynamic.  They call it prusik cord. 

https://www.bluewaterropes.com/product/dynamic-prusik-cord/ just found this ! 

That is it. Several companies make it. I have a spool of the 7mm.  You just need to find a shop that sells it by the ft. I would sell you some of mine, but you are looking for smaller than 7mm 

You could email hownot2's customer service at contact@hownot2.com - they sell a lot of things by the foot which are hard to find elsewhere in lesser quantities.  

Thanks a lot for the help guys!!!!!!
