This holder/organizer is originally intended to hold 5 lipsticks of the brand “banana-beauty” (as a gift), but may as well also hold pens and other things with up to ~17,5mm diameter (depending on your printer resolution).
There are two versions, one with closed rings on top and one with semi-opened ones as it makes things easier to remove.
using supports is highly recommended
