Our glow in the dark collars are cut at a slightly rounded angle dipping towards the clavicle at the front and adjustable in the back with Velcro. Made from soft glow in the dark material wtih a texture like soft latex.
These collars start to glow after only 10 minutes of exposure to sunlight or bright indoor light, (fluorescent is best) but they will glow brightest if you can charge them for at least an hour. The glow in the dark trim must be charged under bright lights for a hour or so before you go out (longer is better) and then will glow softly for a few hours in dark clubs or raves. They maintain their glow brightest in clubs with a black light since this "charges" the glow in the dark chemical really brightly after even a minute of being under black light. So you can go back every hour or so to "supercharge" the glow in the dark trim in club areas with black light.
We have two types of glowing colours Glowstick green (our brightest colour) as shown, and an Aqua green which is a subtler pale blue green colour. If you are unsure and would like to see the colours in person you can add swatches to your order (or order them separately) using our Glow in the Dark Samples page.
