These "matic" toilet rolls are designed to fit the matic style dispensers. These dispensers hold 2 of the toilet rolls one above the other. When the first toilet roll is used fully the core just drops away and allows the 2nd roll to drop into place.
2-PLY Matic toilet rolls are fitted with centre spindles, which, when used with a Matic two-roll dispenser, allow the second roll to drop cleverly into place when the first is exhausted. They are made of luxury pure pulp and each 2-ply roll measures 100-metres in length.
