My friend showed me this black and white flyer for a synthwave show last week. It was just a simple grid of lines forming a mountain shape with the date tucked in the corner. He couldn't stop talking about how that clean look made him actually want to go.

Did the label mention needing proper ventilation?

Yeah that upfront testing really pays off. When you hear @the_derek talk about that payback headache, how do you figure out when a wire is just old versus actually too far gone to trust?
