Glasshouse Night Before Christmas Car Diffuser Refill

Night Before Christmas is the Glasshouse fragrance people wait all year for, and these refills put it in the car. Blackcurrant and redcurrant open it, plum, lemon, lavender and rose sit at its heart, and it settles into musk, oak moss and a little spice. It is rich, fruity and unmistakably festive, a plum pudding of a scent for the drive to Christmas lunch.

The 2026 box is part of Glasshouse's A Very Merry World collection illustrated by Jeffrey Phillips, showing a lavish celebration at a grand British country estate. At under $15 for three disks, it is an easy stocking filler or Kris Kringle gift for anyone who already has a Glasshouse car diffuser.

Night Before Christmas is one of the strongest fragrances Glasshouse makes, so you may like to start with the diffuser turned down and build from there. Each disk lasts around 30 days, so a box keeps the car smelling festive for months. New to car diffusers? The Glasshouse car diffuser gift set includes the diffuser itself, and the fragrance is also available as a 380g candle.

How to Use:

Remove a Scent Disk™ from its sachet. Gently pull the backing off the metal faceplate of your car diffuser, place the disk inside, then click the backing back on with the longer clip at the top. Slide the diffuser onto a car air vent. Turn the body of the diffuser clockwise for a stronger scent and anticlockwise for a softer one. Replace the disk every 30 days or so to keep the fragrance fresh.

Recycling tip: pop used paper Scent Disks™ back into the carton or another paper container before recycling.
