Only use the red one for 1 batch of cake pops (candy melt). The 2nd time I tried to use the red one on white chocolate because the candy melt was too sweet for me. But it didn't work. it was very faded. I dipped the Wilton food coloring gel using the marker to write on the cake pops instead, it took me forever to draw the lines on the cake pops. I had to clean the marker tip every now and then and after that it won't write anymore. Now i store it away, hopefully next time the tip will be wet and able to write again.
