Retro sweet brand Wham is revamping its bars and launching eight products.

The new lines include TNT Popping Candy, a super-sour Xtrm Sherbet Dip, Nitro strawberry & blackcurrant spray and fruity liquorices (rsps: from 10p).

The core Wham chew bars have been enlarged and now include tongue-tingling colour crystals. The bars, as well as the liquorices and lollipops, are also free from artificial colours and flavours.

Further NPD was in the pipeline, said John Sumpner, sales director at brand owner Thornycroft.
