Hunter's comment

The product employs an array of UV LEDs that illuminate a photochromic face while the part of the glowing screen, the material shines at first with response to the LEDs and then it stays ‘on’ after they turn off, showing four numbers.

Hi hunter,

Thanks for your contribution. I’ve reviewed it but can not approve it because this is a manual, not a product/kit.

Yes, we’ve recently reviewed internally whether these hunts should be allowed or not but since they’re not available kits, they are actually multiple products and thus not compliant with posting guidelines, section 2.
