Our children tried to get such pens for school lessons. The local stationery - and bookstores looked this not in a position (the bookstore was outraged because he for around 35 - 12 pins should have ordered). A look at Amazon showed this cheap alternative with convenient shipping. Good merchandise deliveries take longer, but it cost the individual pin below 0.50 because you can sometimes even what to wait longer if you pay only 1/5 of the price. With 12 pins for 5, - is half the class already supplied and all the pins look the same.
