Anti Mosquito Box

Instead of this ugly and impractical wristband, I've made this one for my holiday.
The small one is good for key, key band and car mirror use,
the Ultimate one is also good to use at your belt also and don't need a plug or any second part to use, except for the Mosquito Filament.
(The Filament is 15mm X 48mm with 2,1mm thickness)
