Wheat straw wash cups are made from natural wheat straw fibers. These fibers are biodegradable and renewable, making them an environmentally friendly choice. The texture of the surface facilitates gripping, and while wash cups are primarily used for gargling, they can also be used for other purposes. For example, they can be used for water or other beverages, for toothbrushes. Print your logo on the front to make them easier to advertise!
