Pen Holder, Pen Loop, Self-Adhesive For Notebook, Calendar, Clipboard, Black, Transparent Pad Pack of 3

I tried the Leuchturm version of these penholder loops and found them so tight that getting a pencil through was an effort: fountain pens stood no chance.This item, however, worked well. My (chunky) TWSBI fits, though just a little tight and it's easing with use. I like too the thinness and transparency of the adhesive part: it is barely noticeable and has no impact on the thickness of the diary/notebook.Very good and good value.
