Very nice artwork!
I think NECA went for the packaging they did for the Ultimates because they thought it gave the figures a bit of prestige. However, I do get what you're saying about the velcro closure, they can get a bit dirty after a while on a store shelf. NECA's does fare better than some though. On DML, BBI and SSC they were always falling off. I guess it becomes less of an issue if you only get figures through the mail, which is something I find myself doing more and more, particularly with Mezco as you just can't get them in stores over here.
