子彈筆記筆環

The lightning bolt embossing gives it a nice tactile feel, and the 0.6 inch loop fits my favorite fountain pen perfectly. After a month of daily use, the adhesive is still holding strong on my notebook cover.

The self-adhesive backing holds up really well on my notebook's cover, and the elastic loop keeps even a thicker pen securely in place. The embossed lightning bolt is a nice subtle touch.

Stuck one of these on the inside back cover of my notebook and it's held up way better than I expected. The self-adhesive backing grips tightly and hasn't peeled at all, even after weeks of pulling my pen in and out. Nice that it's small enough to fit without bulking up the cover.
