Recently I've been experimenting with my old edible food pens. Many times I need a very fine writer, but I have not come across anything readily available, very fine, and, well, cheap. This solution works very well for me using Wilton FoodWriters and replacement nibs from Copic, a very fine line of artist markers. The replacement nibs come in many sizes and shapes and are much harder than the tips of many available edible writers, so you get a very thin, beautiful line. This particular replacement nib fits the Wilton pen perfectly. This is how I replaced and refreshed my old pens for pennies! I found this pack of 10 nibs on joann.com for $2.99 (reg. $5.99).
