How important are boxes in this hobby? I don't have a lot of experience about what others do as I've been a solo modelist most my life, but and friend I have husband passed away and so she gifted me these kits that he never got around to building. From what I've seen online they are a bit rare to come by. I'm living in a smallish place and don't have a lot of room for boxes, (I've been labeling and plastic bagging most kits, and putting the finished ones in a display case). Do you think these boxes are worth keeping?
