that is one key aspect of finding the figure. it's also the least conspicuous when trying not to look like an idiot. Shake the bag to one end, the turn it holding the middle, allowing the small things to fall then feel for those. Swords, flat things, tools, etc are the easiest.
Another thing I do to look less like an idiot, if you have smart phone, pull up a page with all the figures shown. Lay the phone on the shelf in front of you, stare at the pictures while slowly feeling the package. AT a quick glance, a person will think you are looking it up to see if you need it.
Same works with the insert from the package.
But if you standing there, eyes closed, feeling away, people are gonna assume you're a freak.
I also learned from that in Victoria's secret.
