Summer Rain Car diffuser refill

The refill slides into the leather case without any fuss, and the scent releases the moment the air hits it—subtle but constantly there. I’ve had mine in for two weeks now and it’s still going strong, which is better than I expected for a tiny cartridge.

The cold diffusion really does work—within a minute of clipping it back in the leather case, the whole cabin smells fresh, not overpowering. I’ve gone through two refills now and each one lasted a solid six weeks of daily driving.

Sliding it into the leather case took seconds, and the cold diffusion really does kick in the moment air passes through. Three weeks in, the scent is still going strong every time I get in the car.
