These are tartan check pants from 666. The size is 30. 666 is a brand I like, and I wore them a bit in the past, but I haven't worn them in a long time due to my age, so I'm selling them. There are no pets or smokers in the house. According to the 666 manufacturer's website, size 30 is listed as follows, but I purchased these quite a while ago, so please consider this as a reference only.
