Does anyone own the Disney Pin Trading Bag (14"x12") or Pin Trading Binder...? I think it's finally time to purchase some sort of Disney pin display item (binder, backpack, etc) as my DD has around 60+ pins and it's time to upgrade from the many plastic lunch bags she's been using for storage. My questions are... 1) Is the Disney Pin Trading Shoulder bag worth it (around $35 + s/h) or do you think the Trading Binder is better. 2) I guess you can't add more storage to the bag, but can you purchase additional sheets somewhere for the binder (I don't want to buy something that will run out of space too soon)...3) I think they both hold around 120 pins (could some please confirm this). ANY SUGGESTIONS??? Thanks in advance!!
