For decades, boxes of Quality Street and then Celebrations have been a staple part of Christmas shopping and a common present for friends and relatives.
But in a sign of the times, Tesco is putting security tags and nets on the products amid the shoplifting epidemic - despite them costing just £3 and £3.75 respectively.
Other chocolate treats also now facing increased security at the chains Covent Garden store include Guylian Seashells, Ferrero Rocher boxes and even Toblerone.
Tesco supermarkets are understood to take an individual approach to security protection, and the policy on chocolate is not universal across all its 2,800 stores.
It comes after Tesco took steps to improve security on other items such as Cathedral City cheese and Dairy Milk bars, which are now found in plastic boxes.

It comes after Yvette Cooper said she was drawing up powers to crack down on shoplifting and street yobbery – after being shocked that even fabric conditioner bottles are being fitted with anti-theft tags.
In an interview with The Mail on Sunday, the Home Secretary pledged to abolish the rule that stolen goods worth under £200 counts as low-value shoplifting with lighter punishments for thieves.

In her speech to Labours party conference in Liverpool, Ms Cooper will accuse the Conservatives of having written off meaningful punishments for other so-called low-level crime, such as anti-social behaviour and criminal damage.
She will promise to put 13,000 more police and PCSOs on the streets, introduce zero-tolerance zones with fixed-penalty fines of up to £500 and bring in powers to seize the off-road bikes increasingly used by criminals.
Last month, retailers called for tougher police action on shoplifting after it was revealed that only 431 fines were issued for the offence in a year.
Figures from the Ministry of Justice show that, in the year to March 2014, 19,419 fines were handed out for retail theft under £100.
This decreased year on year to 415 in the year to March 2023, and rose slightly to 431 in the year to March 2024.
Home Office figures show that 2,252 cautions were accepted for shoplifting in the year to March 2024.

Its latest crime survey showed losses to theft doubled in the last year to £1.8billion, and retailers had to spend a further £1.2billion on anti-crime measures.
