This is a delightful Frontplate for your book nook and, judging from the response it has had in the field when testing it, it is incredibly inviting!
With the Save Watson plate, it comes with an outline of Sherlock himself, and when lit up, casts a tempting reverse silhouette to peer into.
On Air looks like the more traditional On Air sign, and is accompanied by a section of red acetate to either stick to your frontplate, or affix at the front of your set.
There is some minor assembly involved, and you can affix these either permanently, or use the small attached bracket kit to have the frontplate fully removable. Please note that they are supplied as sanded MDF, so can be decorated, painted etc.
