I have the Matador soap container and a set of three soft bottles. You should carefully research the products before buying them. Here are my observations: The flat bottles are a great idea and they'll work well for thick products like creams and lotions. Useless for watery liquids like mouthwash, rubbing alcohol &c. The problem is they have no structure so when the top is opened, watery liquids will instantly gush and splash. I found the little identification labels to be a joke so you might want to figure out a better way to identify the contents. Not recommended. (I have a stupid collection of travel bottles including GooTubes but after testing them all under real world conditions, I revert to my aging flip-top squeeze Nalgene bottles that I got at REI twenty or more years ago.)
The Matador soap bag is an ingenious and practical application of breathable laminated plastic films. You will look at this product and think, "Fifteen bucks for a soap dish? Crazy!" but, I can assure you, the little bag performs its task well. You place your wet soap or shampoo bar in the bag, roll down the top, and clip it shut. Depending on the ambient conditions, in 8 to 20 hours the bar will be dry to the touch. However, if water has penetrated to the interior of the chunk of soap, as happens with my Lush shampoo bars, the object can still turn into goop in a few days.
