Fuji Yacht School Uniform Summer Trousers Size 83

Fuji Yacht School Uniform Trousers - Summer, Size 83
Inseam 76

Stored at home, unused, but the size tag and fabric tag are missing.
There is writing in marker on the inside indicating the size, but according to my measurements, the waist is approximately 83 and the length is approximately 76. The fabric is smooth and I believe it is 100% polyester.

Since there is writing in marker and no tags, I would like someone who doesn't mind this to purchase them.
