Mobiful EC, operated by Union Eternity Co., Ltd., announces the launch of the limited 'Rainy Season Set'—a specially curated car care package that solves multiple vehicle concerns during the rainy season. Available in three customizable variations, the set goes on sale today.

"I just washed the car, and it rains again—what a waste…" "But I don’t want to drive a dirty car…" These are the real frustrations of daily drivers who shuttle kids or run errands. We’ve carefully selected products that deliver maximum cleanliness with minimal time and effort.

Rainy Season Car Washing Isn’t 'Wasteful'! The New Rule: Prevent Buildup Early

Many people wonder, "When should I wash my car during the rainy season?"

The truth is, the most crucial time for care isn’t before the rain—but right after it stops. Early maintenance prevents stubborn water spots and mineral deposits (water spots) from hardening on your vehicle.

This product is a high time-performance (tapa) maintenance kit designed for those overwhelmed by work who can’t spend hours washing their car but still want to maintain a clean, respectable appearance. It’s perfect for finishing touches after using an automatic car wash or for quick spot cleaning.

Choose the Right Set for Your Needs: 3 Variations Available

We offer three sets tailored to your lifestyle and specific pain points:

(1) Total Balance Care – ¥6,390 (Regular Price: ¥9,140)

Contents: Body Water Spot Remover, Front Glass Water Spot Remover, Microfiber Cloth, Quick Air

Recommended for those who want to keep their entire vehicle clean—from exterior water spots and poor visibility during rain to children’s handprints and odors inside the cabin.
