[NAGDU] Clicker that's hard to lose

[Tracy Carcione]

For a long time, I had a clicker on a wristband.  About a month ago, the
wristband broke, and I've lost 2 clickers since.  Can anyone recommend a
clicker that's hard to lose?  Ideally, I think I'd like one I could attach
to the drawstring of my treat bag, without impairing the ability to open and
close the bag.

Thanks.
