KEY FINDER
How to use it：

Attach this electronic key finder to your keys. When you lose your key in your drawer, cupboard, under the bed etc. You can just whistle then it sounds and flashes to help you to find your keys. One high light led helps you to find your way in the dark.

All you need to do is clap, whistle or shout. Any loud noise over 1000-1200hz causes the promotion gift to beep and the light to flash.

Please note that we don't offer color choice, all this item will be picked and packed at random, and some of the finders have no ON & OFF marks on it, but that won't affect the using of it, hope this won't be a big issuer, thanks.
