My order was white strong flexible and I have black strong flexible coming still. They are for classics. I have only one of my classics so far the others are on the way. The Null Reys I have are the white ones I'm intending for Starscream, but he hasn't come yet so it's Acid Storm I'm trying to fit them into to test them. His joints seem tight enough so I'm not sure if it's mold degradation. I'm not sure how I can thicken the pegs up any.
