Day 24 | Lot No R-18

Here's something I am going to have to find out. There's a label on the inside of the jeans that read "Lot No R-18". I understand it probably has to do with the batch these jeans came from, but what is the story behind it? Does anyone know? Does it have to do with the place the denim was made or the place the cotton came from? Why have a label inside the jeans?

The jeans effect from Dr.Denim today is the Short legs effect. Cause: Jeans too long and refusal to alter. Result: Completely ripped bottom hems.
