On Etsy mailebucek123 asked for a side-by-side comparison of the new vs old TARDIS ring designs so here it is:
New style on the left, old on the right
New style in the shadow of the old style
The old rings were hard to wear for everyday use, the new ones will actually let you put your hands in your pockets. The old assembly process often cracked the TARDIS resulting in a blue plastic discard bin that looks like a TARDIS graveyard, the new assembly process it's hard to get wrong. That is why I'm discontinuing and clearancing my stock of old style rings and will only be selling the new style rings.
