Things that Click comes with 100 sounds of unique clicks. The samples include things like mouse clicks, staplers, lids, caps, pens, pencils, light switches and more.
If you've never experimented with foley sounds in your tracks, more specifically in your drum tracks, you really should. Using a unique clicking sample in place of a more standard percussive sound can really make your tracks stand out! I use weird foley sounds in my top loops all the time.
