This is a "Bonbori" (paper lantern). It's opened halfway, like a Chukei fan, and is used in a simplified style. Similar to the Chukei, it's used when wearing color robes and Gojo (five-layered cords), but the Gojo is often not the formal Monshiro (white crest) type, and is often used with Igi Gojo or Sanmon Gojo. ⚠️Images 5, 6, and 7 are of a Chukei fan. Size: 30.5 cm x 8 cm Weight: 50g It is quite damaged. Thank you.
