I have the Art bin one that is a double tote. joann's has it on line I NEVER saw it in person till it showed up. The nice part is the pieces come apart so a normal person can lift them then they slide and snap together for wheeling. The top one opens from the top and the bottom one from the front so you don't have to take it apart when your at a crop. I do because I use the bottom one for my stamps so I open it and then lay it down and then it's easy acess to which set I want.
I'm one of the crazys that takes the ENTIRE room with me, I'm working on that issue but usually mom or my BF will say oh did you bring and I'm like no wasn't planning on using it. So for me I guess the whole dang room will continue to follow me. I use that tote, a navagator and a rolling crate plus a duffle bag, embellie bag, punch box, tool tote and messenger bag. Sometimes Mom even has me drag the laptop and hp printer for a 8 am to midnight crop!!!1
It's insane.......
I can crop with out it all I did a 6 hour crop and only had the navagator, embellie bag, punch box and tool tote and a 2" artbin plastic box.
Good luck to your friend it's a lot to move.
