Boveda Holder 2-Pack Stacked

Swapped out my old single-pack holders for these stacked ones and the airflow improvement is noticeable right away. Installation took maybe two minutes and now my humidity packs stay perfectly in place without sliding around.

I was a bit skeptical about stacking two holders, but the airflow improvement is immediately noticeable in my humidor. The clips are snug and haven't budged at all.

Finally, a simple way to keep my humidity packs from sliding around inside the humidor. The stacked design fits perfectly and the improved airflow seems to be keeping my cigars at a steady humidity.
