CR RNT 728 (Costa Rica) (Road Sign) Color Changing Mug 11oz

This design is a plain, text-led tribute to Costa Rica, built around the country's name and a single alphanumeric code.

Visual Elements & Composition

Nothing decorative competes with the lettering. The words Costa Rica carry the design, with the identifier CR RNT 728 set alongside them as a reference line. The layout is spare and direct, with no scenery, borders or ornament, so the eye goes straight to the name and the code. The restraint is the point: it reads like a sign you would pass on a road, clear and unfussy.

Meaning & Symbolism

The name identifies the place, and the code adds a second layer. RNT 728 has the feel of a catalogue entry, the kind of system regional branding and travel documentation use to categorise a location. Put together, the two lines turn a country into a personal record. It suits anyone who wants to mark a connection to Costa Rica quietly, as a tribute to a place rather than a picture of it.

Designed for the Color Morphing Mug

A mug is held close and turned in the hand, so a text design reads at arm's length, line by line, as you lift it. The lettering sits on the cup's curve, so the code and the name stay legible from every angle as you rotate it. The design is also heat-reactive: it stays faint while the mug is cold and comes up when a hot drink is poured in. That gives the name a small reveal each morning, which suits a design built on one word and one code.

Color-changing ceramic mugs with a glossy finish, black exterior, and white interior. Available in one size: 11 oz (≈330 ml). Heat-reactive coating reveals your custom design when filled with hot liquid. BPA- and lead-free, with a comfortable C-handle.

This mug brings a playful twist to the daily coffee or tea ritual. At room temperature, it looks like a simple black mug with a glossy finish. But add a hot beverage, and your chosen design fades into view, showing vivid colors against the white interior.

The ceramic body is durable enough for repeated use, while the C-shaped handle balances comfort and grip. Printing uses sublimation techniques that fuse color into the heat-reactive surface for crisp results when the design appears.

  • Material: ceramic with glossy black exterior and white interior.
  • Size: one standard size, 11 oz (≈330 ml).
  • Finish: glossy glaze with heat-sensitive surface.
  • Printing: sublimation process produces crisp, vibrant colors.
  • Safety: BPA-free and lead-free, suitable for everyday drinks.
  • Effect: design is faintly visible when cold, fully revealed when hot.

Perfect as a novelty gift or a fun personal mug, the heat-reactive design makes coffee breaks more engaging. It works well for morning coffee, afternoon tea, or hot chocolate.

  1. Daily routine: fill with any hot beverage to reveal your chosen artwork.
  2. Gifting: the “magic” reveal makes it a memorable present for birthdays, holidays, or office exchanges.
  3. Office use: sparks conversation while still being practical for everyday drinks.

Note: for best results, avoid designs that rely heavily on deep black backgrounds, as they may blend with the mug’s surface when cold.

Unlike standard mugs, color-changing mugs require gentler care to preserve the heat-reactive coating. Hand-wash only — avoid the dishwasher and abrasive scrubbers, which can damage the finish and reduce the effect.

The mug is safe for short microwave use when heating liquids, but repeated high-heat cycles may shorten the lifespan of the coating. Always allow the mug to cool before washing.

Available in one classic size: 11 oz (approximately 330 ml). It’s large enough for most standard coffee makers and fits comfortably in most cabinets.
