    Cases+Covers vs. Tournament Play

    What setup is right for you?  Here are some suggestions!  There are two main options you need to decide on first; using Cases & Covers, or Covers only, which we call Tournament Play. 

    Cases offers the best protection by fully surrounding miniatures within the case, while Tournament Play offers the most flexibility with easy access to your miniatures for quick deployment. Using our Troop Targets & Magnets will ensure that your miniatures stay securely in place as you setup. 

    Every tournament player knows how important it is to utilize every opportunity at their disposal; Tournament Play gives you the edge by allowing you to deploy your troops fast and efficient like a pro!  With our crystal clear Lucite® acrylic, easily find your units, deploy in a snap, and then grab an espresso as you wait for your opponent. 

    With Crystal Fortress, you can ramp up the intimidation factor before removing your first model!

    4" case necessary for Silent King

    With a 4" case, and a 4" cover, this will fit the Silent King. There isn't a size graph, but it is great that something can fit the model safely as it is a beast. Perfect product for tall models.

    Huge improvement!

    I purchased these as an attempt to get rid of the homemade metal trays in shoe container boxes we used, and I am so happy that I did! I used only covers to assembly my set you see here in tournament style. 1" cover with magnets followed by a 4" cover. This allows you to remove the cover and grab the models without having to reach in and pry them off their magnets. My only complaint is that I feel like I need to spend some time planning my configuration after indexing the models and base sizes I have. I'd love to have some sort of input where I can provide the number of models at each size and have a dynamically generated option for me!

    Great lid!

    Works exactly as expected. One thing I did notice is that the instructions mention a pair of small support pieces that supposedly fits between the two buttress halves of the inner long support. This piece wasn't included and I am fairly certain that is intentional. Seems like a part of an older design that the instructions haven't been updated for maybe?

    I love these!

    These are great for flyers and Knights!

    Looks great and was exactly what my growing tower of cases needed to be sturdy. If your tower is 2 cases wide (2 Orcas or 4 Belugas), a Humpback case should act as the base.

    I even accidentally broke a part (bent it too much during assembly, totally my fault) and Crystal Fortress replaced it for free (I paid shipping and handling). Great product and great customer support.

    I posted a video on Youtube showing the assembly process and how it fits into my case tower. I even show the part where I broke the part so others can avoid my mistake. https://youtu.be/d2x2Vm6oY20

    Perfect fit to cap my 2" humpback I ordered. Easy assembly if done by following instructions and with care and patience.
