I-405 OR Metric Road Sign Coffee Mug Design

This coffee mug features a design inspired by the iconic Interstate 405 (I-405) road sign, specifically as it would appear in Oregon. However, this design playfully acknowledges the lack of metric signage on Oregon's I-405, a nod to the United States' incomplete conversion to the metric system on its Interstates.

Visual Elements

The core of the design is the familiar Interstate shield: a red, white, and blue emblem. Bold, white numerals "405" prominently display the route number. The overall design closely mirrors the standard U.S. Interstate highway signage, instantly recognizable to anyone familiar with American roadways.

The addition of the "OR" underneath the route number, in a clear, easy-to-read font, indicates the location: the state of Oregon. This adds a layer of geographical context to the design, grounding it in a specific location.

The absence of any kilometer markings or a "km" indicator is a deliberate design choice, and this visual element is intended to remind the user about the lack of metric signage in Oregon.

Meaning & Symbolism

The design represents the I-405 freeway in Oregon, a vital artery for the city of Portland. The road sign itself symbolizes travel, connection, and the infrastructure that enables movement. The design also subtly comments on a particular aspect of American history and standardization.

The design also acknowledges the unique quirks of the U.S. Interstate system and the resistance to adopting metric measurements. It reflects a sense of place while hinting at the enduring presence of miles in American road travel.

Sturdy white ceramic mugs available in 11 oz (≈330 ml) and 15 oz (≈440 ml), with a glossy finish and comfortable C-handle — microwave and dishwasher safe, and made from lead- and BPA-free materials.

These mugs are built from durable white ceramic so colors pop cleanly and prints read with strong contrast. A smooth, glossy glaze gives each mug a lively sheen and makes it easy to wipe clean after daily use.

Both sizes feature a classic C-shaped handle that feels natural in the hand; whether you sip slowly or gulp quickly, the grip is steady. Safety-wise, the ceramic is processed to be lead- and BPA-free — suitable for everyday drinking.

  • Material: white ceramic with a glossy glaze for bright, clear prints.
  • Sizes: 11 oz (≈330 ml) and 15 oz (≈440 ml) to suit small and generous pours.
  • Handle: comfortable C-handle for balanced holding and easy lifting.
  • Safety: lead-free and BPA-free for peace of mind with every cup.
  • Finish: glossy surface that highlights saturated inks and smooth detail.

Perfect for morning coffee, afternoon tea, or a rich hot chocolate — these mugs fit comfortably in most cabinets and cupholders. They’re also a reliable choice for office kitchens where items see frequent use.

  1. Everyday use: safe for hot liquids and daily serving; the wider 15 oz option works great for larger morning routines or extra-steamy drinks.
  2. Office-friendly: the classic profile stacks easily with similar mugs and sits securely on standard saucers and trays.
  3. Gift idea: a practical, well-finished mug is useful and simple to display or wrap for gifting.

Quick note: while the mugs are dishwasher-safe, treating them gently helps keep the print looking fresh longer (see Care tab).

These mugs are rated for microwave and dishwasher use, but small habits extend their life. Run them on the top rack of the dishwasher and avoid high-temperature commercial cycles whenever possible.

For longest-lasting print clarity: hand wash with mild dish soap and a soft cloth, avoid abrasive scouring pads, and don’t let them soak in strong detergents. When microwaving, use short intervals and avoid empty heating.

Available sizes: 11 oz (approximately 330 ml) and 15 oz (approximately 440 ml). The 11 oz is a classic coffee size; the 15 oz gives extra room for cream, froth, or larger servings.

Each mug has a standard-width mouth for easy sipping and cleaning; height and diameter vary slightly between sizes to maintain comfortable proportions and sturdy balance.
