What's blue and goes VWORP?

Now this thing you see here, it is my TARDIS
Out whether which I'll get this party started.
Time And Relative Dimension
In Space - it's quite an invention.
Some call it The Doctor's Wife,
Excuse me while I slip inside!

These are the lines from the trock song It's Bigger on the Inside. And this *points up* is my brand new TARDIS model. Whew! *rubs sweat off the forehead* Now it serves as a container for my Whovian treasures like sonic screwdriver models. The pattern on the inner side of the cover was borrowed from one of works: fav.me/d91z7ii Wanted to add those wee little details as well, but couldn't find the required charms, so I left the writing as it is.

Materials used:
- multi-colored beads (mat blue, glittering indigo, see-through with rainbow glitter, white, black, watery blue, see-through, dark grey);
- nylon thread;
- hardback paper (for the walls, floor and cover base);
- wooden chopsticks (to fix the corners);
- cotton wool (to fill the cover's top and light).

Measurements:
- height (with the top) - 32 cm;
- height (without the top) - 22 cm;
- length - 15 cm;

Well, what would you say?
