As I recently discovered a nail varnish that is a stunning TARDIS blue I just had to do a #BookishNails recommendation! The colour of this varnish is actually called Sonic Blue, instead of TARDIS blue, but there’s absolutely NO freakin’ way that that’s just a coincidence because it’s definitely the colour of the TARDIS (but obviously they can’t call it that). The varnish is by COLLECTION as part of the 7 Day Wear line, & is number 23; I only needed two coats for this colour to look great & I’m really happy with its durability. As always, I used Nail Growth Miracle as a base coat & an Insta-Dry top coat (both by Sally Hansen). I love this colour & it’s definitely one of my favourites.
