Molotow ONE4ALL Marker Shock Blue

I’ve repainted a few plastic planters and a metal toolbox with this shade, and the opacity is genuinely impressive—no ghosting from the old colors underneath. The fact that the system is refillable and UV resistant makes it feel like a long-term investment rather than a one-off art supply.

This marker lays down color so smoothly and evenly on plastic, which is usually a pain to write on. The refillable system is a huge plus, and the blue is incredibly vibrant and opaque.

The opacity is impressive—this marker covered a dark plastic surface in one pass with no streaks. The cap fits snugly and the tip hasn't dried out after a few weeks of use. Shock Blue is a vibrant, solid color that pops without looking cheap.
