Pistola stacked button jeans Size 4? NWOT Possibly sample or concept design

Pistola stacked button front jeans. I bought these at a boutique section and a woman there said she believes they got them straight from the distributor and thought by they might be a sample or a concept Jean from 2019 for their Caleb design potentially. They do not have a size tag but have a hand written tag (see photo) with style info. I can’t find any info on them but would be curious is if anyone knows what the handwritten tag means and why it is different and doesn’t have fabric tag:) I believe they are a size 4ish. Please see photos for additional size details. They do have some stretch but I am not sure the exact fabric content %’s. Interesting Jean. I haven’t seen many stacked button front so thought they were cool and unique. I found this info on brand samples: Brand samples but may or may not have size tags. however, they may be missing care/material tags inside and may have handwritten sample hang tags. (This is what this appears to be). Curious if anyone knows more? I might have paid too much for these but I was curious with the tag and liked the unique stacked design. :)
