Italian Marble Paper Napkin Ring

Napkin rings from IL PAPIRO, a specialty store for marbled paper in Italy. I received these as a gift but am selling them as I won't be using them. They have been opened but are unused.
Each piece has a unique pattern, drawing you in the more you look at it. They appear to be resin rings in a calming brown tone, likely adhered. Set of 6.
Photos 4, 5, and 6 are for reference.
May be opened for packaging.
