As a huge Demon Slayer fan, I was thrilled to get my hands on this Tengen Uzui Katana building set. The moment I opened the box, I could tell this wasn't your average toy - the vibrant colors and detailed design instantly caught my eye.

The building process was surprisingly smooth. While it took me about 4 hours to complete (with some snack breaks!), the instructions were clear and each piece fit together perfectly. The satisfying 'click' when blocks connected made the experience even more enjoyable.

What really impressed me was how sturdy the final product turned out. The dual blades have just the right amount of weight, making them feel authentic without being too heavy. They look absolutely stunning displayed on my shelf - though I do agree with other reviewers that the stand could be more stable.

I've had friends over who couldn't believe this was made from building blocks until they got up close. The chain detail is particularly impressive and adds that extra anime-accurate touch that true fans will appreciate.

While it's marketed for ages 6+, I'd recommend this more for teens and adults due to the complexity and number of pieces. It's become one of my favorite collectibles - perfect for display or light cosplay use (no vigorous swinging though!).

The only minor downside was finding a couple extra pieces left over after completing the build, but nothing crucial was missing in my set. For the price and quality, this is definitely worth it for any Demon Slayer enthusiast looking for a unique building challenge.
