The iRiver 8GB Domino USB Memory Stick is designed like a domino block. Simply slide out the USB connector out of the block when you need to use it. To protect your connector, slide the USB connector back into the block to keep it from breaking. You can also use this block as a cellphone strap so you won’t ever lose it! The iRiver 8GB Domino USB Memory Stick also offers a strong password protection program so that no unwanted eyes can get into your files!
