It’s easy to get carried away- look at how well these cubes stack and fill my suitcase! But when you bring too many cubes, you are more likely to fill the cubes with articles of clothing that you really don’t need.
I mentioned it before; the big ones are often a bit too big in my opinion. Plus they might not fill the space of your luggage in the best way possible.
If you don’t fill your cubes, then there still may be room for the items inside to shift around and get extra wrinkled. If you overfill them, then it could make it difficult to repack, and let’s not forget about the extra stress on the zippers and bag itself.
You can definitely use packing cubes for more than just clothes, but chances are there is a much better packing container for things like cosmetics and electronics cables, and even bras.
Sure, it’s a bonus if you are able to fit more stuff into your carry-on because you’ve compressed said stuff in packing cubes. But fitting more in means you have heavier luggage.
Regardless of whether or not your airline allows the extra weight, we at HPL are adamantly opposed to extra luggage weight and bulk for more reasons than just saving money on airfare. It’s important to focus on the organization features of packing cubes.
