Good to know

It stands about 3.9 ft (120 cm) from the snow clouds at the bottom to the top of the topper. Measure the wall you have in mind before you order: it looks best with a little clear space on either side and nothing in front of it.

It goes up with the 3M adhesive strips in the box, no nails or drilling. If your paint is new, delicate or textured, try a small piece on a hidden spot first.

It runs on batteries (not included), so there is no cord or plug. Press the button on the back to turn it on and off.

The Present Trail is our favorite: a glitter gift box with a teddy bear peeking out, spilling a trail of tiny presents down the wall. Santa's Sleigh and the Flying Reindeer are the classic Christmas Eve pair, and the Christmas Train is full of little details for kids to spot. Choosing two? One on each side of the stairs looks beautiful, and two trails save 10%.

No. It is made for indoor walls only. Keep it out of rain, damp and steam, and well away from candles, fireplaces and heaters. The snow clouds and ribbons are soft decorations, and they belong on a cool, dry wall.
