As with the music wire products these CF lengths are only available as part of an order for Model Plane Foam. They will be shipped in the box with the foam. We can't ship CF separately at these prices.
If you order a box of foam, you can order CF, there is no minimum order and there is no bundle requirement, so order the exact quantity you need. But Please do not order any by itself, even though the Paypal form will let you do it.
