London:
Britain's royal wedding is still four months away, but the first official memorabilia went on sale on Monday - a range of wedding china personally approved by the couple.
Prince William's office said the items had been commissioned by the palace department responsible for the royal family's art collection and made in Stoke-on-Trent in central England, a traditional centre for British ceramics.
The three souvenirs - a tankard, plate and pill box - each feature the couple's entwined initials, the prince's coronet emblem and the date of the wedding - April 29, 2011.
On sale at royal palaces and a website, profits from the collectables will be donated to the charity which curates the royal family's artworks, known as the Royal Collection.
"The Royal Collection has been working on the design since around the time of the engagement - it's a very fast moving process," William's office said in a statement.
His office said that the prince and his future bride had both approved the wedding merchandise.
William and Kate Middleton made their first public appearance on Saturday since announcing their engagement, attending a cancer charity fundraising event in eastern England.
The couple are to be married at Westminster Abbey on April 29 after a lengthy courtship.
