Verbatim Store 'n' Go USB key with DHO key attached, 24GB total (16GB + 8GB)

HI, Lost my USB key in IT Tallaght approximately 18/2/2013 some time between 6:30pm and 9:30pm up in room 216. It has a keypad on the door you need to know to get in. It was presentations that night. I don't normally bring a key around. I must have taken it off my person to get my slides running. It took me a week before I noticed it was gone. Hope you can help me get it back. Total, two keys lost. One is blue, bigger than the smaller white one. Also has a distinctive pouch holder and a small climbers carabiner (oh the irony). Very particular. No others like it that I've ever seen. If found, please drop it in to the IT tallaght caretakers. I'll replace the pair for a 32GB USB 3.0 model in the meantime which I would be happy to offer as a reward.
