Body Bar Container with Brush and Drainage

We would like a compact cylindrical container (around 10cm in diameter) with a lid and a removable drainage board. This container is to store a refillable soap that will rest on the draining board and, on top of that an exfoliating body brush. The lid must fit on with these layers inside. We would like each component to be made of bamboo, with the brush bristles being made of bamboo. However, we are open to other materials as long as they are waterproofable and sustainable - the main focus of our project. The diagram attached does not include the bottom drainage board (which the soap will be placed on), however, this is a key component we would like to include in the product. Please let me know ASAP if you're interested or any further ideas you may have - we are very excited to work with you!
