I went through every item on the 3d item list



as of Jan, 09, 2023:
By "Price"
Anime hair is the most expensive item, costing 200k
Poker hat is the least expensive item, costing only 1k

By "Owned by"
Old Eastern Hair is the least owned item, being owned by only 12 people
Sodehair is the most owned item, being owned by 1100 people

By "Total":
There's a total of only 9 Sumo Hair
There's a total of 6537 Black Belts

By "Total in circulation":
There's 274 Black Belts in circulation
There's 0 Steampunk Hammer, Sword in Stone, Jetpack, Old Eastern Hair and Sumo Hair in circulation


I don't understand the difference between the "Owned by" and "Total", I believe it's a difference between having it on your inventory and actually having it active, but I'll have to test it out later.

I'll attach the xlsx file in a zip file, as xlsx is not supported for upload rn, and update the OP.

Because of the above, I will put up the Black Belt as the most popular 3D item, and all item popularity will be decided based on this number.

I decided to go ahead and do the same for Forces, I may do the relaxes tomorrow
