Butt but'r can be had in small packets.
If you NEED it, you'll be glad you have it. Sometimes gas stations will have triple antibiotic ointment which is better then nothing in a pinch...
I've NEEDed it and not had it, and worn through the skin so it looked like road rash or a burn. Stung like heck every pedal... So a packet or 2 sits in bottom of pack now...
Not needed it in a long time now, but gonna go check pack to be sure it's still there...
