You are the ultimate Green Samaritan until the sniffles strike home. Then you blow it by reaching for a box of tissues.

Spare trees and rid boogies the old-fashioned way with Snottykins handkerchiefs. Created by a Santa Barbara mom, the cloths are made in the USA of sustainable organic cotton. Choose singles or multipacks of kid-size squares emblazoned with cheeky designs (trains, monkeys, and more, in your choice of color). Grown-up snot rags come with more refined motifs like sailboats and doves.

The hankies get softer with each wash, making the torturous task of toddler-nose blowing more bearable.

That’s nothing to sneeze at.
