Like New/Good Condition 30 OZ Stanley Tumbler

Preowned Good Condition Stanley 30 OZ Tumbler with handle Color-Pool includes a straw 100 percent Authentic I used this Stanley Tumbler for 6 months at the most. The Tumbler has been cleaned throughly. I originally paid 35 plus shipping online. On the front of the Tumbler, there's some black lines. I do not know what this is . I wouldn't say they are scratches, but just some light marks. I tried to get them off the best I could but still visible. The bottom of the cup has some scratches/chipped paint. Despite these flaws, the Tumbler is still in good condition and doesn't affect the function of the cup. Please see all the pictures for reference! I didn't see any other damage. I will ship within one day and package with care. Comes from a smoke-free /pet free home.
