DIY Educational Luminous Castle Building Blocks Toy Set for Kids STEM Learning

The luminous effect isn't as bright as glow-in-the-dark stars—it's more of a subtle shimmer under normal light, so don't expect a nightlight-level glow, but kids still love it because the castle looks like it's lit from within during dim play.

For US and EU buyers, we've got teh EN71 and ASTM F963 certs ready to go with every shipment, and we usually include the customs-friendly packing list and SDS if needed—just confirm your port when ordering so we can flag the right docs.

105 pieces in a purple castle build that ends up about 22cm tall, and the blocks are a standerd size that works with most major brands, so you won't get complaints about compatiblity—just note the 3+ age rating means small parts are inside, so it's not for toddlers who still mouth things.

We ship these in a 26x15x35cm box with a manual inside, and the MOQ is typically 500 units or so for a mixed pallet, but our company can do a trial order of 200 if you're testing a new market—lead time is usually 20 days or so form order confirmation.

Actually, one thing we've noticed is that the luminous elements are embedded in about 30% of pieces, not all of them, so some buyers think the whole set glows—it doesn't, but the castle towers and roof parts are the ones that catch the light best.

Anyway, most distributors go with the purple because of that it stands out on shelves, but we can do other colors if you're ordering a full container—just don't ask for custom molds unless you're committing to 10k units or more.
