I just received this. I purchased bags in medium and large.First, I packed my makeup, - a lot of makeup into the medium bag and used another previously purchased different bag for my toiletries. Makeup fit it perfectly. I rarely use that much makeup but it did pack an enormous amount of stuff. The small bag would be best for less makeup.Second, I tried packing the large bag - all the same makeup and all the same travel toiletries from the firat trial run with 2 bags. It fit it all easily in the Large bag. It's not super tall and bulky so it would fit in a suitcase well.Third, although I'm not a fan of these velcro dividers, but did separate out a few things. Trick here is to secure from bottom to top of wall and make sure the wall is pulled taught. Fits well.I'm going to try it and see how it performs travelling for 2 days.Now, one con is this is cloth including the handle which, isn't ideal for travelling to hunid climates. It will absorb moisture and isn't wipeable. It could potentially be washed on gentle and air dried.
