Project Soapbottle is a soap dispenser made from soap. The idea itself is simple. What is inside is the soap itself. If you cut a part of the soap, you can use liquid soap. After using the liquid soap, you can use the soap in the package as it is. This eliminates unnecessary waste such as packaging and containers.
Since it is a bottle made of soap, its use is of course limited, such as not being able to use it for other contents. Nevertheless, it can be said that it is a unique item, such as helping to reduce plastic.
This product also raised funds through Kickstarter, a crowdfunding site. More information about the product can be found here.
