Awesome looking set!
on August 14, 2026

[This review was collected as part of a promotion.] I haven't had the time to put this together yet, but I am so excited get this started. We have assembled several Mattel brick sets and the quality is great. Instructions are easy to follow and the finished products always look great. This Masters of the Universe set looks awesome. The skull is absolutely amazing. It comes with 16 figurines which seems like a lot. Can't wait to add the finished product to my collection.
I would recommend this to a friend!

Something fun to do with your kids!

[This review was collected as part of a promotion.] We received the Mattel Brick Shop Masters of the Universe Battle of Castle Grayskull Building Set and I have to say, it is really fun to put together with family! This set is more a display piece than just putting it together and then playing with it. We ended up putting it in a case to display on my husbands streaming channel. I highly recommend this set if you like he-man and want to do something fun as a family.

fun for older kids

[This review was collected as part of a promotion.] It was challenging and age appropriate. My oldest loves legos and was excited with this set. It was smaller than typical legos. It was not hard to fit pieces with larger hands. The instructions were detailed and easy to follow. My younger child was playing with the figurines in the castle.

Battle of Castle Grayskull
on August 10, 2026
Posted by: EDLG
from Philadelphia, PA
[This review was collected as part of a promotion.] I started building this with my 13yo son being a huge fan of MOFU growing up and was very excited when it arrived. First, the set is gorgeous. It’s an amazing likeness of the castle and very detailed gave us hours and hours of building fun. Definitely not for younger children. The pieces are actually pretty well designed and the guide was very easy to follow. I will be looking to pick up other sets in the collection as they become available

Amazing toy details
on August 9, 2026

from Staten Island NY
[This review was collected as part of a promotion.] This toy is really fantastic! The amount of details to the characters and scenes are very well done. It’s like a Lego piece, so every piece of the scene needs to be built and put together. All the pieces come in their own bags and instructions to build are very clear and easy to follow. We were able to build this with our 8 year old.

Nostalgic He-Man castle, fun build!
on August 4, 2026
Posted by: texasmamabear
from Texas
[This review was collected as part of a promotion.] I had so much fun building this set and it kept me busy for several hours! I love brick sets and have assembled a lot so I had high expectations for this and it exceeded them! The two side towers rotate and the back panel with He-Man can also spin around dramatically. There are tons of mini-figures for acting out the battles and they have bright colors and can be placed on the bricks for poses. I loved that the instruction book had large, clear pictures and highlighted each new part of the build so it was easy to follow along. The book also had fun background stories and Easter eggs. The bricks were glossy, lots of unique colors and shapes (loved the creepy pointy teeth at the skull opening and the foliage), and they fit together nicely, not a single missing piece. I will definitely be looking out for new sets, these are fun. This will get more gameplay with my family and then be displayed on a shelf.

A Very Detailed Albeit Challenging Build
on August 1, 2026
Posted by: kisetta
from Rochester, NY
[This review was collected as part of a promotion.] This castle will make a nice addition to our collection! The set itself requires great attention to detail - we learned quickly that the instructions must be followed exactly and sometimes you need to go back a step and connect it in a different place then they want you to to ensure it stays together but once you do its fairly solid (make sure you push them together). The smaller detail pieces can sometimes disconnect easily so it is not a set for heavy play. The turrets of the castle and the shrine all rotate which is really neat and the gorilla face can move as well. The shrine can be stand alone or be attached to be part of the castle. The figures have great detail (and the set comes with quite a few) and fit into the set very well. The set includes 14 bags most of which have small pieces so it takes some work to put it together and it is definitely for children over 13 MINIMUM. As an adult I had to assist several times and many pieces look like each other so its very much like assembling an intermediate puzzle. Take your time and you won't be disappointed. The build itself is smaller (9'' high by 10'' wide) than I expected but it is nice once completed. I think to save your sanity, unless you have someone that does these builds a lot, its best to complete over several days.

Fun but small

from New jersey
[This review was collected as part of a promotion.] The pieces are pretty small which is fine for an older kid but they are smalled than lego figures. This is our first mattel brick shop playset but its just smaller than expected and difficult to play with.
No, I would not recommend this to a friend.
