I remember them, huge bars as well. and they are back, but Nestle have had the cheek to put a huge stamp on the packet "Blast from the Past" but they are less than half the size of the original one, that really sucks as well. Its also worth mentioning they are no anything like the ones I remember, the toffee was fairly hard initially and the chocolate always flaked off when it bent, these ones are rubbish, and 4 times the price.
i currently have one sitting in front of me. i couldnt believe it when i saw in the shop. im saving it to show my brother. hopefully the shop will start selling splicers also.
