About this gift

A partner's birthday is the hardest gift slot in the calendar — you have already used the obvious thoughts on Christmas, the anniversary, Valentine's Day and three previous birthdays. A chart mug is a way out. It is specific (one bay, one estuary, one approach, drawn in line), useful (it makes tea every morning), and decided by the place that means something to you both. Mounts Bay if you got engaged on the Mount. Helford if your first weekend away was Frenchman's Creek. £14.99, made to order in Cornwall.

Why a chart for a partner

A chart mug is the gift that says you remember a specific place. The line is drawn from a real Admiralty chart and shows soundings, named headlands, lit buoys and the coast as it actually runs — which means a partner who knows the coast at all will pick up the picture before they read the base. We sell more chart mugs as partner gifts than as any other recipient category. The reason, judging by the messages we get with orders, is that a chart locks in a memory. The Helford estuary mug has been bought eleven times in 2026 alone with a note saying it was the place of a first holiday or a proposal. We have shipped Mounts Bay mugs to twelve partners whose first kiss was, apparently, on the causeway out to St Michael's Mount. Whether or not that is true in every case, the chart works as a memory anchor in a way a flowery card does not. The price holds at £14.99 — the line never gets re-priced as a so-called premium partner gift, which is a small but real signal: it is the same mug we sell to a sea swimmer or a kayaker. The picture is what makes it specific, not the price tag.

Why a Cornish illustrated mug

The chart mugs in the line are drawn from current Admiralty sources, simplified to three colours, and fired under-glaze in a small Cornish pottery. The under-glaze method means the line of the chart is part of the ceramic surface; it does not lift, scratch or fade. The ceramic is a standard 11oz white body — not a thin novelty mug — and the handle is sized to take a man's grip comfortably (a small detail, but one we get notes about). The studio is in West Cornwall, the pottery is in mid-Cornwall, and the boxes leave a post office in Penzance. Each chart mug ships within 3 days of order; UK delivery is typically 2-4 working days from dispatch. The base of every mug carries the studio mark, the chart number (where applicable) and the year of the source chart used. None of this is decorative. It is the same set of conventions a printed map carries; we keep them on the mug because they tell the truth about the picture.

The charts we draw

Helford estuary is the romantic favourite: a six-mile inlet on the south coast with oyster beds at the head and a passenger ferry at the mouth, drawn from Helford Passage on the north side. Frenchman's Creek (du Maurier's creek) sits halfway up the chart and is named on the mug. Mounts Bay runs from Mousehole around to Praa Sands with St Michael's Mount sitting in its tidal causeway. Falmouth Approach is the working anchorage south of Pendennis — a hard-working chart with tanker buoys, the Black Rock, the line of the Lizard in the distance. Carrick Roads, the deep channel from Falmouth to Truro, is the quietest of the south-coast charts. Padstow Bar is the difficult one — sandbanks that shift every winter — and the Land's End to Scillies chart is mostly open sea, which is the point. If the place you share with your partner has a chart in the line, the picture is the picture. If it does not, we are slowly adding new charts (St Ives Bay and Fowey Harbour are in the 2027 plan).

Buyer notes

  • Holds 11oz, one of two if you want the pair.

Questions buyers ask

Can I pair two charts as one gift?
Yes — buy any two from the line for £22 (multi-pack price). Two charts side by side, packed in a single kraft box. We have sent quite a few "where we met / where we live now" pair sends.
Will it arrive on the day?
Order at least 7 working days in advance for guaranteed UK delivery on a specific day. We do not run paid express on this line — the kiln cycle does not allow it.
Do you do international shipping?
Yes — Europe and North America. Shipping is calculated at checkout. EU buyers pay the destination VAT at delivery; we do not collect it at the door.
