What does a cock ring do? A cock ring sits around the base of the penis and applies gentle pressure. That pressure slows the flow of blood out of an erection, which can help it stay firmer for longer, and many wearers say orgasm feels stronger with one on. A stretchy silicone ring like the Firefly Halo is the easiest type to start with, because it goes on and comes off without effort. As general guidance, wear one for no more than 20 to 30 minutes at a time.
Firefly Halo: the cock ring that glows
The Firefly Halo from NS Novelties is a plain, non-vibrating cock ring with one twist: it glows in the dark. It is made of soft, stretchy silicone that gives a snug but comfortable fit around the base of the penis. The maker designs it to help with staying power and a stronger climax.
The Halo is sold here in two sizes, medium and large. The distributor lists the medium ring as clear and the large ring as blue.
Best for: For men who want a simple, comfortable ring for longer-lasting erections, and for couples who like to play with the lights off. Soft, stretchy silicone makes it friendly for first-time ring users. Choose medium for a tighter hold and large for more room.

How to use
Hold the ring under a bright light for a few minutes if you want it to glow. Rub a little water-based lubricant on the inside of the ring. Stretch it open with your fingers and roll it down to the base of the penis while soft or partly erect. It should feel snug, not painful. To wear it behind the testicles as well, pass them through one at a time first. Take it off after 20 to 30 minutes, or straight away if you notice numbness, coldness or discomfort.
Care
- Use water-based lubricant; silicone lubricant can damage a silicone ring.
- Wash with warm water and mild soap after every use.
- Dry it fully and store it away from other silicone toys.
- As general guidance, do not wear a cock ring for more than 20 to 30 minutes at a time.
- Remove it at once if you feel pain or numbness, and never fall asleep wearing it.

Frequently asked questions
Should I choose medium or large?
The maker does not publish diameters for either size. As a rule, medium gives a firmer squeeze and large is more relaxed or suits a thicker penis. The silicone stretches, so both have some give. If you are new to rings, the large is the gentler start.
Are the two sizes the same color?
No. According to the distributor, the medium Halo is clear and the large Halo is blue. Both are made of the same glow-in-the-dark silicone, so the size you choose also decides the color you get.
How do I get it to glow?
Expose the ring to light before use. A few minutes under a lamp or in daylight charges the glow, which then shows when the room goes dark.
How long can I wear it?
General guidance for any cock ring is about 20 to 30 minutes at a time. Take it off sooner if the skin feels cold or numb or changes color, and give yourself a break before putting it back on.
Does it vibrate?
No. The Halo is a plain stretchy ring with no motor. Its job is the fit around the base of the penis, with the glow as an extra.
