♡Mizuho♡, Thank you for your continued patronage. I have increased the number of beads and adjusted the inner diameter. Upon checking the size, it is approximately 16.5 cm. To get closer to 16 cm, some of the gold appearance will be lost, but there is also the option of removing two small spacer rondelles. What would you like to do? Please consider this. I look forward to your reply in the comment section. Thank you very much! ^_^♡ Color: Red系 (Red-based) Scratches/Discoloration: None
