No, we do not offer this product with custom length options.
Yes, you can cut the fibers to any length using a household pair of scissors. Simply cut the fibers, and they will have the same effect where cut.
End glow fiber optics have memory and will conform to whatever shape they are stored in. We recommend storing your fibers loosely curled within a bag or hanging it straight down from the top of your closet door. See our tutorial on "Fiber Care and Maintenance" and "Transporting and Storing" for more.
Yes. Regular washing is encouraged to keep dirt from diminishing the brightness of the end glow fibers. See our tutorial on "Light Whip Cleaning & Lubrication" for more. 
Your ORBIT BITWHIP or FYBER KIT may develop unwanted curls or straightened fibers. If that's the case, then you'll want to adjust how your end glow fiber optic product is stored. This is because end glow fibers will conform to the shape that they are stored. If you want more curls, then store the fibers curled. If you want straighter fibers, then hang the product from your closet door until the fibers straighten out. 
DO NOT expose them to temperatures that cause the plastic to melt. This will deform the fibers and cause them to bend. If you do want to use heat to manipulate the fibers, use the heat source on a small sample size of the product. If you like the effect, then you can apply it to the rest of the fibers. Melting or bending fibers is not reversible.
