Funny Math Lover Ceramic Coffee Mug with Calculus Equations Design, Humorous Science Teacher Student Gift Cup, 11oz or 15oz

About this mug

A white ceramic coffee mug with a glossy glaze, printed to order, in 11 oz or 15 oz. The 11 oz is the size most people picture when they say mug; the 15 oz is noticeably taller and suits a long morning or a large tea. Both share the same 3.35 inch diameter, so either one fits a normal cup holder and a normal dishwasher rack.

The handle is a proper C-shape with room for a whole set of fingers — not the pinched little loop on cheap promotional cups that forces you to grip the hot body instead.

How the design is printed. Sublimation, not a decal and not a sticker. Under heat the ink turns to gas and bonds inside the glaze itself, so there is no printed layer sitting on the surface: nothing to catch a fingernail, nothing to lift at the rim, nothing to go grey after a month of dishwasher cycles. Run a finger across the design and you feel glaze, not ink.

Everyday use. Dishwasher safe on the top rack and microwave safe, because there is no metallic trim to arc. The print wraps the full body with a gap behind the handle, so it reads whichever hand picks it up — worth knowing if you are buying for someone left-handed.

Made after you order it. Each mug is printed individually once the order arrives, then packed in moulded protection for the post. Ordering six with six different names is no different for us than ordering one: they are printed separately and arrive together.

Looking after it. Dishwasher and microwave are both fine. The one thing worth avoiding is a scouring pad — abrasives dull the glaze over time, and the glaze is what carries the image.

When will it arrive?

Questions people ask

Will the design wash off in the dishwasher?

No. Sublimation bonds the image inside the glaze rather than printing it onto the surface, so there is no layer that can lift. The top rack is still gentler over hundreds of cycles, mostly because of how hard the jets hit the lower one.

Is the design on both sides?

Yes. The print wraps the full body with a gap behind the handle, so it reads whichever hand picks the mug up.

11 oz or 15 oz — which should I pick?

11 oz is the standard mug most people already own and is right for a normal coffee. 15 oz is noticeably taller and better for a long morning or a large tea. Both are the same diameter, so either fits a normal cup holder.

Is it microwave safe?

Yes. There is no metallic trim anywhere on it, and metallic trim is the thing that arcs in a microwave.

Can I put a name or a photo on it?

If this product offers personalisation, the fields appear on this page. Upload the image at the largest size you have — it prints at roughly 300 DPI, so a small screenshot will come out soft.

What is it made of, and how big is it?

White ceramic with a glossy glaze. The 11 oz is 3.85 inches tall, the 15 oz is 4.69 inches, and both are 3.35 inches across.

Does it come in a box?

Every mug ships in moulded protective packaging. If one arrives broken, send a photo and we remake it — there is no need to return the pieces.

How long until it arrives?

Two to four business days in production, then three to seven business days in transit within the US.

Can I order several with different designs?

Yes. Add each one to the cart separately; they are printed individually and arrive in the same parcel.
