K1 colored powder dyes have now replaced the dyes I've used for several years. They are POTENT. Word of caution...they will stain your hands, comes off in a day or so...gloves might be advised. Also, make sure you cover the kitchen counter when using them...a little water and the slightest bit of powder goes a loooong ways. I had the counter top covered so don't know if it'd stain it...but, I wouldn't chance it.
Colors I used...purple, blue, yellow and white...all did great but was particularly happy with how WHITE the white powder made the boilies, and this was using a very tan basemix and a purple flavor.
Thumbs Up K1...great dyes.
