Kobayashi Pharmaceutical Co., Ltd. (Headquarters: Osaka City; President: Kaeichi Toyota) will launch limited-edition summer packaging for its toilet fragrance and cleaning agent 'Blue Let Stampie Antibacterial*¹ Fragrance' in two popular scents—'Fragrance Floral' and 'Fragrance Osmanthus'—on July 23, 2026 (Thursday), available nationwide for a limited quantity.
Development Background
In recent years, summer temperatures in Japan often exceed 40°C. Even indoors, toilets tend to be poorly ventilated and become hot and humid. As temperatures and humidity rise, odors tend to accumulate, making it crucial to maintain a comfortable toilet environment during this season.
The 'Blue Let Stampie' series is widely used not only for preventing black stains but also by consumers who start noticing unpleasant toilet odors. To attract new users who have not yet tried the series, this launch features limited-edition packaging with enhanced visibility.
Product Features
- Inhibits the formation of black stains at the waterline and provides 99% antibacterial*¹ protection
Simply stamp the gel onto the toilet surface, and each flush gradually releases a cleaning agent infused with antibacterial*¹ ingredients. This antibacterial*¹ formula helps prevent the buildup of black stains*², which are often difficult to clean. Using two stamps (one on each side of the bowl) provides approximately 12 days of use, with one bottle lasting about 45 days (based on 10 flushes per day)*³.
*1 Inhibits the growth of bacteria that cause black stains. Does not eliminate all types of bacteria.
*2 Effectiveness may vary depending on usage environment and level of dirt. Black stains may still occur during use.
*3 Duration may vary slightly due to water temperature, air temperature, and water volume.
- Two floral fragrances to refresh and brighten your toilet space
In addition to the classic 'Fragrance Floral,' the recently launched 'Fragrance Osmanthus' offers two delightful scents to make your toilet more pleasant and inviting.
【Fragrance Floral Scent】
A vibrant floral-fruity fragrance combining roses and jasmine with soothing chamomile and bright, fresh fruity notes of apple and pear.
【Fragrance Osmanthus Scent】
A floral-fruity fragrance centered on the rich, elegant scent of osmanthus, blended with juicy apricot, orange, and peach, and enhanced by transparent rose, freesia, and jasmine. Soft sandalwood and iris add a comforting sense of cleanliness.
