this is the best sample test kit if you're new to this sort of thing. I got a binder about 2-3 years ago and its tough for me to put on and take off. Plus, my weight & size fluctuates to an extreme extent so sometimes it doesn't bind at all :( but the instructions, website, and recommended materials is really useful. I like the visual infographic, especially useful for those who struggle reading blocks of information like me. I like the suggested materials to remove or apply like cotton as nip covers and the oils to assure safe removal. I can go on and on. This is perfect, srsly. Discrete looking packaging too
