OptiLube Tubes - Sterile Lubricating Jelly for Insertion of Medical Devices in 5g, 42g, 82g, and 113g Tubes, Water Soluble Lubricant with Easy-to-Use Flip Cap (5g x 48)

I use this for my silicone custom-mould earplugs from ACS and it works a treat. Quite thicker than the ACS supplied comfort cream, it kind of "fills" the remaining gaps in your ear canal, for a more snug fit. Without the lubricant, my ears get very irritated by the earplugs, but with this, they just slide straight in (and stay there all night). You can get about 7-10 days use from each tube too, so these will last you a long time. Highly recommended.

we use these in our clinic. They are easy to use in the small tubes.Very prompt delivery.
