Guitar picks! They are the worlds most frequent items to get lost. You want to jam a little with this great new tune you just came up with but your guitar pick is nowhere to be found. Do not worry, you do not need to use the coin or go to the store to buy new. Just make your own pick in seconds from some old old credit card, gift card, hotel key card, ID card, any plastic material or from sheets of popular materials like Delrin, Lexan and Ultem.
