I have about 15 Guerlain Rouge G style ones and bc of that I know that they don't fit regular rectangular holders or even glass ones. What I use instead is just a few glass boxes like https://www.amazon.com/Hipiwe-Vintage-Glass-Jewelry-Trinket/dp/B07TXP62R9/ref=sr_1_51?keywords=glass+box&qid=1649352409&sr=8-51
