Query: very pleased

is a joy when you find simple solution to vexing problem in life. (one being not having working pen handy when needed) This product has solved that problem. These pens write cleanly, smoothly, are a joy to use, and getting so many for such a decent price, is such a gift, thank you so much for this product. Bringing me joy where there once was stress, thank you!
