  1. Good quality review by Sarah
    Product Rating

    Our drawings required Cellcore CC, but was advised by Lemon that that has been replaced with Cellcore HXB. Everything worked fine, its surprisingly strong for polystyrene.

  2. Much improved review by Stephen
    Product Rating

    The new Cellcore HXB is much better then the previous Cellcore. The older product (Type CC) was bits of polystyrene glued to the underside of the plastic, but it is now moulded as one section. This makes it much stronger, and when you cut it to length, it doesn't fall apart. I still think the product is expensive, but it is good quality.
