Repackaged Soap Bar
Here’s another great idea that I gleaned from scanning the BackpackingLight Forums: using the plastic container from an old bike tube patch kit as a soap bar container.
Whole soap bars tend to be far too large and heavy for any but the longest of travels. Cutting up a bar of soap to make it smaller is easier enough, but prior to this I had never come across a correctly sized container to package it in.
This container is perfect. It measures in at 3.25” x 1.75” x 0.9”, weighs 2.5 oz when full, and holds about 1/3rd of a bar of Dr. Bronner’s Bar Soap. I wrap a rubber band around it for added security.
