About these numbers
Months of supply
Under 3 months is a seller's market, 3 to 6 balanced, over 6 a buyer's.
How this is measured
Poshmark listings live on the date the block shows (every seller, not only Closo shops), divided by an average month of the 12-month sales in “What K18 hair sells for”. Asks are listings up for under 90 days — a listing up longer is left out of them; a sold price is the item's last listed price, not the accepted offer.
K18 Hair — questions buyers ask
Answers come from live Closo listings and real sales, not from marketing copy.
