Bandages

From the Comic

Cotton bandages are clearly well outside the price range of the average citizen in Trinity. Fortunately, there's been some innovation into cheap synthetic absorptive materials over the centuries since The Withering, and multiple Houses (including House Wright) offer a dizzying array of low(-ish) cost bandages. With medical supplies being the #3 commodity sold in Trinity after food and fuel, it's a lucrative business to be in. (From Ep 1 Act 1 Page 4)
