The Seal of Naperville, Illinois is the official symbol representing the city's government and authority. It embodies the historical, cultural, and civic identity of Naperville. The seal features a shield divided into four quarters, each quarter symbolizing a significant aspect of Naperville's history and development: agriculture, industry, education, and community. The top left quarter showcases a sheaf of wheat to signify the city's agricultural roots. The bottom left displays a hammer and spindle to represent the growth of industries. The top right quarter features books to symbolize the importance of education in Naperville, while the bottom right quarter depicts a tree to represent the city's commitment to community growth and unity. In the center of the shield is a bison, which was chosen as a nod to the Native American tribes who originally inhabited the region. The bison is encircled by the words "City of Naperville," emphasizing the city's name and authority. The seal is completed with a scroll beneath the shield bearing the motto, "Naperville: A Hometown for All Seasons." This motto underscores the appeal and charm of Naperville as a vibrant and welcoming community throughout all four seasons. The design of the Seal of Naperville reflects the city's rich history, its growth and development, and its commitment to education, industry, and community. It serves as an enduring symbol of Naperville's identity and spirit.

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.

  1. Daily use: fill with your preferred brew and sip — the mug handles hot liquids safely.
  2. Office-friendly: fits most standard mug warmers and sits securely on communal trays and kitchen counters.
  3. 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.
