100% recommend! The seller was super helpful when I wasn't sure whether these would fit in my file cabinet. They do fit and they are super high quality. I love the colors being visible alongside the numbers, it helps me ensure that I don't switch things around by mistake.
I added small carabiner clips to the holes and then I'll put the floss into floss a way bags and put them on the carabiners. I didn't want to pre-cut floss because I usually loop start but occasionally I'll use 1 or 3 strands so I would want longer sections. The bags allow me to keep the floss intact until I'm ready to use it. I can also put several skeins in the same bag.
