This is Kobayashi Pharmaceutical's "Hair Catcher Poi." I am selling this because the drain shape no longer fits after moving. A box of 16 contains 16 unused pieces + 11 additional pieces, for a total of 27 pieces. The box is labeled as "16 pieces," but it actually contains 27. ・Kobayashi Pharmaceutical Hair Catcher Poi ・Contents: Total 27 pieces (packaged in a box of 16) ・Condition: All unused ・Use: Catches hair in the bathroom drain Please understand that the number of items inside the box differs from the box's label before purchasing. Thank you.
