Display Card with 12 Bambi switchblade Keychain knives all Original

Vintage Display card with 12 original Bambi style switchblade keychain knives still intact. Not sure on the age of this, but I believe it to be from the 1980s or 90s and made in Hong Kong. The little knives all seem to work okay. This is something you don't often get a chance to buy. The keychain knives usually seem to sell for $25-35 ea. Like New condition. This is for the complete card with 12 keychain automatic knives.
