I climbed Ben Nevis (the UK's highest peak) as part of a fundraiser for Muscular Dystrophy UK.
In the spirit of NASA astronauts, I carried a "Personal Preference Kit (PPK)" of items in my backpack. I took them out at the summit and even signed a few things.
On offer here is one of 4 Unmade Podcast Guitar Plectrums (Plectra?) that made the trip.
They will come with a little certificate/card signed by me to confirm their authenticity.
All profits from the sale will go directly to the Muscular Dystrophy fundraiser.
