Maths Birthday Card - Pi Thon

Pi Thon


(2 customer reviews)

Everyone’s got that one friend who’s memorised the first ten or so numbers in Pi. Well now you can celebrate them! Or beat them at their own game, however you want to play it.

We all sat around a very very long calculator to squeeze 57 numbers onto this snake fellow. We think he looks quite jazzy.

Want to make your mathsey friends hiss with giggles? Give them this exssssssellent card and they will be secretly shaking their rattles! Best served with a big slice of Pi (omm).

And if you’re into black holes, come check out our Science Lab dog greetings card, that pooch is definitely on track for CERN membership.

A Bit About This Collection : This is an au natural science birthday card, right down to the envelope. No frills here, just some good ol’ puns and a splash of paint. We have printed this range onto recycled paper, so it looks good and does good! We particularly love this board; because it is recycled there are very small flecks in the card giving it a natural but smooth look which gives the design even more texture and a luxe feel. This maths birthday card is an original illustration in a mixture of dip pen & ink, gouache, watercolour, and fine liner.

Size:  120mm x 170mm in size (a bit bigger than A6!)

Envelope: Your card will come with a brown kraft envelope. 

Materials: Designed and printed  sustainably in the UK onto 300gsm Revive recycled board.

Recyclable: Both card and envelope are fully recyclable.
