The American based company, Mondelez International, posted a message on their Toblerone Facebook page about the reduction of the two bars, the 400g and 170g weight ones.
They wrote: "Toblerone remains one of the best value and most delicious Swiss chocolate products in the market.
"This is because we always work hard to ensure we offer value for money for our consumers, but like many other companies, we are experiencing higher costs for numerous ingredients.
"We carry these costs for as long as possible, but to ensure Toblerone remains on-shelf, is affordable and retains the triangular shape, we have had to reduce the weight of just two of our bars in the UK, from the wider range of available Toblerone products."
The message was posted almost three weeks ago but it seems that the story is getting traction now as word of mouth spreads and the new bars hit shelves.
So what do you think? Fair enough, as many companies cutting costs or increasing costs post Brexit vote and pre-Brexit implementation? Or the bars just look silly and they're on their Tobler on this one?! (Bad? Or good bad?!)
