The sachets are usually better, usually cheaper than buying the jar separately. I love these metal lids from Taymac. . I originally bought 1 for a place I wanted to work at and ended up making my whole house. I don't understand why anyone uses clear plastic bottles. They look a lot cleaner once installed and just feel like they'll last a lot longer (polycarbonate would probably work, but I think it will cloud over time as you clear).
