You can buy a larger version on amazon. That's what I have. I bought a green plastic scrubbie and cut it to fit so any guck accumulates on that instead of oozing out in my bag. I'd link the soap dish I bought but it isn't available anymore. Not that surprising since I purchased it ten years ago. I'm sure there are other versions still available, though.

Edit: Found a version of the soap dish with holes. The one I have is more similar to the ethique container but I'm now certain just by searching soap dish with holes and lid you can find something.
