I have two similar kits, one I use for traveling, and one I keep at work. As others have mentioned, I include a small pack of dental floss as well as a few individually packaged toothpicks I snag from restaurants. Other items I find useful is a small zip lock with a dozen or so Q-tips and a small stainless nail file. Over the years I have added and subtracted items, but have settled in on these Items.

• Small Bar of Dr. Bonners soap (used for the minimal shaving I do)
• Small travel sized Shampoo
• Tooth Brush
• Tooth Paste
• Dental Floss
• Toothpicks
• Deodorant
• Metal Nail File
• Q-Tips
• Disposable Razor
• Hair Comb

I find the bulk/weight negligible, and as with selecting most stuff an individual’s personal preference.

I carry these items in a small MOLLE pouch (both kits) but I like the looks of the OPs roll up, where did you get it?
