It comes in various colors including, white, red, blue, green, yellow, teal, magenta, rose gold, and purple; and sizes ranging from a meter to 4 meter. Can also be ordered in 300 feet spools for bulk construction. It is easy to work with as a plug and play and easy to sew into wearables with the tab provided along it's entire length.
The LEDs are waterproof with a cap for washing, and the company claims that it is strong enough to be pulled on the long axis up to 66 pounds. I keep wanting to try it myself, but haven't had the chance and I'd rather sew it and use it than break one by hanging it.
Splicing it is a little difficult due to the smaller wire size, but someone skilled in soldering should be able to do it fairly well. I recommend and use a modified linesman's splice for all my splices to give it some added strength. I also recommend a fray check or quick drying glue to clean up the yarn after splicing.
This is one of my favorite products and I plan to use for numerous other designs.
