Nielsen's Heuristic .03 — Haiku Edition Ceramic Mug

User Control and Freedom, the third of Nielsen’s usability heuristics, advocates for giving users the ability to reverse, escape, and recover from actions — without penalty or friction. It’s a core UX principle rooted in dignity and autonomy: systems should never trap, confuse, or commit users to unwanted paths. From undo buttons to cancel options and emergency exits, control builds confidence.

This beautiful ceramic mug is perfect for any event of the day. Your morning coffee, a hot chocolate, or any other hot beverage you enjoy. The mug is glossy white with a colored rim, inside, and handle. The prints come out beautifully and vividly on it. The print retains its quality and luster when used in both microwaves and the dishwasher.
