Customized old ear plugs: custom molded ear plugs catty a label showing a noise reduction rating or NRR. If you mold and wear custom molded earplugs in accord dace with the directions, the noise entering the ear will be reduced by about 26dB

Do it yourself:
1.Clean ears and wash hands thoroughly
Dirt and debris will affect the cure rate of this product, have a mirror ready before beginning
2.Gently remove material from each container and divide into two equal portions, store the remaining halves in their respective containers
Keep the colored and white material separated until ready to begin the molding since mixing the two will start the curing process
3.To begin the curing process, knead one of the colored halves andwhite halves together vigorously for 30-45 seconds or until streakfree
Roll into a ball
4.Keeping your head level, gently press material into one ear by pushing in the center of the silicone, fold the excess in and press the center again several times.Silicone will then conform to your ear’s contour forming a good seal.Fill outer ear as completely and smoothly possible.A mirror is helpful to render a smooth outer surface and finished look, any excess material not needed to fill outer ear during molding can be pinched off before totally cured and discarded.Do not press material too deeply into the ear canal, do not chew or talk during RHIS process.Once a uniform, consistent plug is formed, let plug cure for a minimum of 10 minutes in the ear, allow longer if formed plug is still pliable
5.A properly formed ear plug will have a smooth outer surface, closely contour to the ear partially extend into the ear canal and fit snugly
6.Do not remove plug from the ear for a minimum of 10 minutes,once cured, gently remove plug by slow
