This is a simple 2-piece travel soap dish sized for a round shampoo bar from Lush. I made it without drain holes so it wouldn't leak inside luggage. I think the plastic is porous enough that it should dry out over time and the base dish can just be washed out before travel. The top is made to fit snugly and is slightly oval so that it stays put. There are a couple of flats on the cover that you can pinch together to help get them apart. There is also an oval version of this design.
