About this design
IRL L4023
IRL L4023 (Ireland) (Road Sign) Black Coffee Mug
This design reproduces a road route marker plate: a single rounded rectangle carrying the code L4023, set against a clean, flat field of colour.
Visual Elements & Composition
White dominates the design, filling roughly four-fifths of the surface, with black taking the rest. The plate sits centred with generous margins, so nothing competes with it. Its stadium-cornered outline gives it the familiar shape of a roadside sign, and the black, bold sans-serif lettering reads L4023 in a single line. There are no ornaments, gradients or background scenes. The flat vector treatment keeps every edge crisp, which suits a composition built on contrast and restraint.
Meaning & Symbolism
Route markers exist to be read at a glance, and this plate does exactly that. The alphanumeric code is the whole message: the letter L marks the road class within Ireland's numbering system, and 4023 identifies one specific route among the many that thread the island together. The design connects the country to its roads rather than to landscape or legend, so Ireland appears here as a network of places you travel between. Its minimalist, utilitarian language reflects the way official signage is designed to communicate without decoration.
On the Black Mug
A mug is turned in the hand, so the plate will come around the curve in pieces, with the code appearing as you rotate it. The black and white palette holds its contrast on every side of the cup, and the simple layout means the lettering stays legible from the handle to the rim. It is a quiet design for a morning ritual: something to read while the kettle does its work, and a small, cheeky nod to anyone who has ever followed a road number across Ireland and wondered where it leads.

Glossy black ceramic mugs in two practical sizes — 11 oz (≈330 ml) and 15 oz (≈440 ml). Comfortable C-handle, microwave- and dishwasher-safe, and manufactured to be lead- and BPA-free. Note: printed blacks may read slightly different from the mug’s base color.
These mugs are made from solid ceramic with a glossy glaze that gives a deep, even surface for printing. Sublimation printing embeds ink into the glaze so artwork sits smoothly on the mug rather than simply sitting on top — that means better resistance to fading and scratching during normal use.
They’re available in the classic 11-ounce size for everyday black coffee and tea, and a larger 15-ounce cup if you like extra room for milk, foam or a long pour. The C-shaped handle is wide enough for a secure grip and balances the mug well when full.
- Material: 100% ceramic with a high-gloss finish for punchy, saturated results.
- Sizes: 11 oz (≈330 ml) and 15 oz (≈440 ml) — choose your routine size.
- Printing: sublimation process fuses color into the glaze for durable imagery.
- Safety: lead- and BPA-free; meets common food-contact safety standards.
- Design note: very dark artwork and the mug’s black base can produce subtle shade differences — add a thin lighter outline to ensure contrast if needed.
These mugs are at home in the kitchen, on the office desk, or tucked into a morning routine. They work for espresso shots, pour-overs, oat-milk lattes — you name it. The larger size is handy when you want a second cup’s worth without a refill.
- Daily use: fill with your preferred brew and sip — the mug handles hot liquids safely.
- Office-friendly: fits most standard mug warmers and sits securely on communal trays and kitchen counters.
- Gifting: packs well (wrap with a soft layer) and pairs nicely with coffee beans, tea tins, or a small box of biscuits.
Practical tip: for very dark designs, try a thin light border or a small margin so the artwork reads cleanly against the black ceramic.
These mugs are both microwave- and dishwasher-safe, but gentle habits extend the life of the print. We recommend dishwasher use on the top rack and milder cycles when possible.
Hand-washing is the friendliest option: warm water, mild dish soap, and a soft sponge. Avoid steel wool, harsh scouring pads, or blasting with extremely hot industrial cycles. And a quick reminder — don’t microwave an empty mug.
Two sizes: 11 oz (approx. 330 ml) and 15 oz (approx. 440 ml). The smaller cup is the familiar, everyday size; the larger one is for fuller pours and extra-creamy drinks.
Each mug’s mouth and height are proportioned so they’re easy to drink from and easy to clean. If you’re pairing with saucers or nesting in cabinets, expect the 15 oz to be slightly wider and taller than the 11 oz.
