Our usage tips
How to use the Cobeco Fist Assist Butter 500 ml oil-based lubricant
- Check the material before you start. Gloves must be nitrile, and toys must be made from an oil-resistant material.
- Take as much as you want and apply it directly to your skin or to the toy.
- Start with a little and add more if you need it. As it doesn't dry out or absorb quickly, you don't need to reapply often.
- Go slowly and stop if you feel pain.
- Put a towel underneath. The oil can stain sheets and other fabrics.
After use
Close the tub tightly after each use and store it somewhere cool and dry, away from sunlight. To remove it from your skin, use warm water and soap.
Our tips
- Don't use it with condoms or latex gloves. Oil-based lubricants damage latex.
- If you have sensitive skin, first try a small amount on the inside of your arm and wait a while.
- If you notice itching, stinging or irritation, stop using it and wash the area with water.
- Wipe up anything that drops on the floor straight away, because it's slippery.
- A lubricant is not a contraceptive and doesn't protect against sexually transmitted infections.
