There's a much easier way to ensure no blockages and it's very economical at the same time, use old postage stamps, all you do is get the stamp and fold it in half then fold in half again, you then tear off the corner and put the piece you tear off to one side, open out the stamp and there will be a hole in the centre, poke your finger through the hole and then use that finger to do the required wipe at the rear, you then slide the stamp off your finger which in turn will remove any material collected and drop it in the loo, the little piece you put to one side you then use to clean under your finger nail, absolutely no chance of blocking the loo and your recycling used stamps.
