The Castellax Battle-automata are general purpose combat robots, developed from older designs during the Great Crusade. Primarily intended for siege work and shock assaults, these terrifying, humanoid machines stand three times the height of a man, with notoriously aggressive and responsive machine spirits. The Castellax class is a mainstay of both the Legio Cybernetica and the elite defensive formations of many forge worlds, who rely on its formidable power, armoured endoskeleton, and atomantic shielding technology for their protection.

This multipart plastic kit builds two Castellax Battle-automata, core constructs of the Mechanicum in the age of the Horus Heresy. Each Castellax Battle-automata can be equipped with a pair of claw-like shock charges, or one may be equipped with circular power blades, and each may equip a choice of in-built bolters or flamers for either weapon. The kit also contains a choice of shoulder-mounted weapon options – you'll find two mauler bolt cannons, as well as a darkfire cannon and a multi-melta.

You can further customise your mechanical monsters with a choice of three different arm joints for each automaton, plus joints in their waist and shoulders, allowing you to create a variety of poses. Should you choose to arm your automata with shock chargers, you can choose to have their claws gripped shut, or open and ready to grab the enemy.

This kit contains 191 plastic components, and 2x Citadel 60mm Round Bases. This set also includes 1x Mechanicum Constructs Transfer Sheet containing 558x high-quality waterslide transfers for you to use to customise your miniatures.

These miniatures are supplied unpainted and require assembly – we recommend using Citadel Plastic Glue and Citadel Colour paints.

Heavy linen character, but a beautifully tailored suit!
Color: Beige, Size: 4, Color: Beige, Size: 4
This is a really nice linen suit! The jacket is beautifully made and well-tailored, with a fun speckled texture that has lots of pretty color variation (we ordered the beige). When I placed it side by side with a similar linen suit from another brand, the difference in the linen texture was really noticeable — this had a much stronger linen character that stands out! It has three useful pockets on the outside of the jacket, which is great for little hands. The only downside is that one of the inside pockets is just for show (faux), which was a bit surprising and somewhat disappointing for my little guy. The pants have pockets too, but they aren’t very deep — perfect for small treasures, but not much more. The pants are made from a lighter, thinner single-layer linen compared to the fully lined, double-layer jacket, which makes sense for comfort and easy movement. The pants didn’t come with a front crease ironed in, so you’ll want to press one yourself. The linen did pick up some creases from being folded in the package, but it doesn’t seem quite as wrinkly as some other linen fabrics I’ve tried. Still, like most linen clothes, especially for boys, the pants will need occasional ironing to keep them looking neat and crisp, especially after a day of play and general wear. The structured, lined jacket stays looking smoother and more put-together with less effort. It also came with a bow tie, a neck tie, and a tuxedo-style white shirt as extras. The ties aren’t great quality — they’d work fine for quick photos but probably won’t hold up to much actual wear. The formal white shirt feels a bit funny paired with the casual linen suit, but I don’t mind at all. We already have white shirts that we prefer, so we’ll use those instead. For us, the extras are really just bonus items we won’t plan on using. Overall, it’s a handsome little suit that’s perfect for special occasions like weddings, family photos, or holiday events. My kid looked adorable in it! The stronger linen texture on the jacket gives it a premium feel that I really like. Just be ready for a bit of extra care with the pants to keep everything sharp.

Great suit set
Color: Light Grey, Size: 4
It is incredibly attractive and includes everything a young child needs for a special occasion. The material is a 75% polyester and 25% linen blend, and the outer fabric feels remarkably smooth. Its unstructured design allows for an attractive, natural drape, and the blend conveniently allows for machine washing at home. As is typical with linen-based materials, the fabric can be naturally stiff and prone to wrinkling, so I recommend ironing or steaming it before use. The lightweight feel makes it an excellent choice for the spring, summer, and fall months. Overall, this suit offers exceptional value for the price.

Samsonite? I was way off!
Size: 8, Color: Light Blue, Size: 8, Color: Light Blue
Linen was a nice enough material and slightly distracted from the dumb&dumber blue motif. The regular suit material would have been a full homage. It is what he wanted so this was a fair compromise. Stats/ he is a size 8 in most brands, 51in and 60lbs. Purchased an 8. A size 7 would have been a better choice and more tailored look but this fit fine in the important places and he has room to grow. Short notice, quick shipping and fair quality for the price. May your Harry Dunne love it as much as mine did.
