When Purolator changed their logo and can designs a couple years ago and took away the textured grip, the P1 and Boss came in 6-sided boxes, while the Classic (now painted red) retained the regular square/rectangular boxes.
But as of early 2018, the P1 doesn't come in that six-sided box anymore. Here is a 2018-production P1 box that is a normal box shape, along with some older stock filters in the six-sided boxes:
Apparently, the best-selling filter at Kmart seems to be the PL14459
The PurolatorONE blue can with the red gasket looks so pretty. Just too bad they still tear.
