Because who doesn’t love a bit of irrational precision?

Looking for the perfect gift for a maths lover, engineer, or science geek? Our Pi Slate Coasters are made from high-quality Welsh slate sourced from the mountains of Snowdonia and laser-engraved with the digits of Pi — spiralling beautifully to 250, 500, or even 1000 decimal places.

This is more than just a coaster; it's a conversation starter, a nerdy delight, and a celebration of infinite numbers. Whether you're sipping your morning coffee or hosting a geeky dinner party, this coaster brings character, charm, and just the right amount of chaos to your tabletop.

Available individually or as a stunning gift set of three, boxed and ready to impress.

Coaster Dimensions:

  • Diameter: 82 mm
  • Material: Welsh Slate
  • Backed with protective felt pads

Purchase Options:

  • Single coaster (choose from 250, 500, or 1000 digits)
  • Set of all 3 (with free gift box)

Note: Due to the natural nature of slate, some texture and edge variation may occur, adding to the uniqueness of each piece.
