The customer for the forbon models above wanted red twine on the coil, but black tape can also be used, and tape is better for allowing more space on the ends, which is at a premium on humbucker-sized P90's (ask any winder). As you can also see with the end shot, the bobbin is a bit taller to help with the end space. The forbon set above was made all-A5 and 9.3k/7.2k. The set in the LP in the top photo are the same specs except the bridge is 5/2 rather than all-A5. The plastic is not as soft as the forbon so the extra A5 is not needed to get the sizzle.
The forbon models are still $90 per pickup, but the black and cream plastic are $105. (The plastic is a bit less forgiving than forbon.)
90-Buckers are available in black or cream!
