Review title is Difficult to clean out [SEP] The accordion aspect of the two travel bottles is a bit awkward at first when actually using them, but overall functionality is fine. They have nice big openings for easy transfer of product into the bottles or cream jar. No issues with leakage for me. However, I did find it difficult to clean out the accordion bottles. Not sure if it's because of the multiple internal grooves from the accordion design, but it took a lot more rinses and shaking the bottle with water and soap in it to get it clean, for me, than I prefer.
