## Emma's take

Starts cool, warms with friction, lasts for hours.

This is the lube that teaches you patience, in the best way. Spark goes on with a cooling sensation from the menthol, then builds warmth as things heat up. It's designed for those marathon sessions when you want something that truly lasts without any sticky breakdown. The silicone formula stays slick through water play, and that cooling-to-warming progression adds a layer of anticipation that makes everything feel more intentional. Fair warning: it may stain lighter sheets, so maybe save the good linens for another night.

## Frequently asked questions

## How long does the warming sensation last?

The menthol creates an initial cooling feeling that gradually warms with friction and movement. The warming sensation builds throughout your session and can last as long as the lube itself — which is hours.

## Is this safe to use with all toys?

It's compatible with glass, metal, and hard plastic toys, plus latex condoms. However, silicone-based lubes can potentially degrade some silicone toys over time, so test on a small area first or use a different lube with silicone toys.

## Will this stain my sheets?

Yes, silicone-based lubes can stain some fabrics, especially lighter colors. Use a towel underneath or save your favorite sheets for another night. The formula is designed to last, which means it doesn't wash out as easily as water-based options.

## How much should I use for the first time?

Start with just a few drops — this formula is highly concentrated and a little goes a very long way. You can always add more, but you can't take it back once applied.

## Is the menthol sensation too intense for sensitive skin?

The menthol is food-grade and designed to be stimulating rather than overwhelming. If you have very sensitive skin, test a small amount first. The cooling sensation is gentle and the warming builds gradually with friction.
