PLEASE NOTE: This item will ONLY work with FEMALE AVIES! It will not work with Male avies. There is a separate version for Male avies available in the catalog. It will also conflict with any item that replaces the avie's hands, like gloves and certain weapons. Please -> use TRY IT before you BUY IT! There will be NO REFUNDS if you buy the wrong version by accident, or this doesn't work with your existing outfit.

Don't like Red? Wish those air punches made some noise? Well then DERIVE IT! Make your own version, and even sell it the catalog for a small markup over my original, and you can keep the extra profits for yourself! You can express yourself AND earn credits at the same time. How's that for a sweet deal? You'll need a full account on IMVU, as well as a copy of Previewer. You can find out more about Deriving on the IMVU's Education Center.

To add sound, I highly recommend you download and use Audacity. It's a free sound editing tool that can export out OGG sound files. OGG sound files compress down to less then 1/10th the file size of WAV files. SO USE OGG FILES!!! You can download it here:
