Louis Vuitton difference between neverfull Mm bag, neverfull Gm bag, & Pm bag

1st photo is a mm size, 4 lv’s on the bottom of the bag. 2nd picture is a gm size, 5 lv’s. On the bottom of the bag. 3rd picture is a pm size, 3 lv’s on the bottom of the bag. I have noticed a lot of bags on here that have the wrong size listed. Ask the seller to post a full picture of the bottom so you can confirm the size they are selling. Last picture is the neverfull style bag. Just trying to help 🥰 Do not buy! This goes for all Neverfull bags regardless of year! The patterns stay the same for the size!!
