BlackSquare Technologies chose the new Klearfold Keeper visual packaging system to launch their Enigma USB Hardware Encryption & Decryption Device. Klearfold Keeper effectively showcases the Enigma, revealing the thumb-sized product in its entirety, which helps to demonstrate its simplicity and ease of use. The patented Klearfold Keeper combines a printed rigid plastic sleeve and a uniquely designed vacuum-formed tray that lock securely together to produce a distinctive, efficient and secure visual package.
