Sooooo... somewhere i missed that this is a giant canvas bag on wheels, that only had shape of you keep the original tree box.  We tossed the box so have our trees laying in it so it is difficult to store as things cannot be stacked on top. Total user error on my part. Canvas  zipper are good quality. Wheels work well. Also a bonus that there is a strap worth clasp to hold the tree in place in the bag.
