My collection's in various plastic tubs around my house, but every TF I have has been liberated, at least once - I keep the Takra Collection ones in their boxes (mainly because I have alternates to most of them), but they have all breathed fresh air at least once in their lives.....I don't know - I don't buy them for monetary value, or with resale in mind so it doesn't really seem a big deal to me to open them.
