I have been curing in cardboard boxes that I punch holes in the sides of. I was under the impression that I needed airflow during curing. Is that not the case? I could easily not poke holes if that would help me to maintain some of my EO.I second trying to reduce airflow to maintain scents! I store mine in closed cardboard boxes.. Also, stay away from top notes, those are the most notorious faders. Find some middle and base notes and you'll be fine for at least 6months up to a year when stored in a place with limited airflow.
Now that my nose got un-blocked I went back to smell the soaps.
Highbrow still has a faint but pleasant smell (at 9 months) while Rocker only gives off a bit of smell when washing with it (at 13 months)
Just for the record I only started storing my soaps in boxes a few months ago (after finding out how much it affects scent retention), so my review is based on mixed storing conditions.
