Thanks Paul.

I saw a video on youtube last night that showed how the lid goes on and comes off...much better perspective now.
I'm not concerned about theft prevention...just about using those "thingies" and needing to take them off more than once after I *think* it's all packed, since A) I can't leave my house without returning to get cell phone, library books, etc, and B) we once had to buy two pairs of scissors on the same day when we were leaving to come home from WDW because we had zip-stripped the suitcases closed and needed to put more in.

Better to have something we can put on/take off...repeatedly.
