I know we have seen these sort of things before but I wanted to share my results
ok finally got some new easy to roll bags lol We went to Target and picked up 2 small Swiss Army luggage toats. We then placed an order for 4 sets of Pelican pick and pull foam and went to work (forgot the #). Works amazing and for the total coast ($180ish) for both and we were able to get 2 bags that work amazing. Similar bags go for about $300+ each Best of all we don't look like photographer we look like we have a small amount of luggage lol also the large case has a pocket for a 17in laptop
