Levi'sMen's 501 Original Fit Jeans (Also Available in Big & Tall)

Hi dear supplier, Just one question: Be honest please, Is it made in Mexico or Colombia? thank you.

what is the number of the same jeans with a zip fly

Are these jeans shrink to fit or pre-washed?

I have older 505 with a 15 inch leg openning. Which current Levi cut is closest to it?
