Born in the Barn create a range of customisable, removable d20 dice necklaces with a wide range of options. If you're looking for something authentic and rustic feel to add to your TTRPG gaming collection, take a look at their wooden random generators, dice trays, and even rollable pencils. They also offer beautiful USB stick potion bottles filled with red resin, so you can store your files in the nerdiest way possible.
