Popular Professional Jab-Jab Clean This is a powder detergent for cleaning one-hole bath heaters, containing Agent A and Agent B. A cup is not included, so it's for repeat users who already have a cup. I'm selling one portion at a low price because the cup wouldn't fit my bathtub's structure, so I couldn't use it! - Contents: Agent A 200g, Agent B 300g - Made in: Japan - Purpose: Bath heater cleaning - Type: Powder detergent Thank you for looking.
