Tupperware sells them!

Thank you.

I use microwave sterilizer bags. They can be found in the baby section at Walmart, or you can order them online.

Thanks for that— do you use for aerobika?

Love knowledge gained from others!!! Thanks everyone!!

Still looking for large collapsible bowl to use when traveling. I would need it for cleaning/soaking aerobika and nebulizer in warm, sudsy water as well as using it for rinsing on a daily basis. Just wanted to free up room in my carry-on luggage as bowls that collapse take up such little space. Would need to be microwave safe. Can't seem to find any that are large enough.

If you can’t find a Tupperware Consultant you might check on Amazon. They have several large ones. Good luck.

@judyhodgern Hi Judy! Nice to see you. ❤ How are you doing these days?

Pet supply companies also sell the collapsible water dishes. May have a large enough size made for big dogs.

Will try. The trick is to find one that is microwaveable. If discover, will let all know. Still trying to get in touch with a Tupperware representative as well. Thank you all for the suggestions.

The one I use ("Munchkin Latch") looks like a heavy-duty freezer bag and measures 8 by 11 inches with a base that opens to about 5 inches so that the bag stands upright in the microwave. I can put a disassembled nebulizer and my aerobika in one.
