We've been moving a fair number of these lately, and the 5210 model is the one that keeps coming back. Most buyers go with the color box for retail, but the OPP bag keeps the price lower for mixed orders, roughly 3 pieces is the minimum.

It's basically a Notre Dame in miniature, those ABS pieces click together better than some of the cheaper alternatives we've tested. The tolerance is tighter than most generic building blocks at this price point—you'll feel it when you're connecting the flying buttresses or teh central spire. What it does is develop spatial reasoning and patience, though it's not for very young kids, 8 and up is the right call here. One detail a buyer might not think to ask about: the instructions are printed on a single sheet, not a booklet, so you'll want to check that if you're selling to a less patient audience.

CE and UKCA are covered, we've got the COAs ready to go with each batch. Actually, the ABS is eco-friendly per the current standerd, though that's more a production claim than a performnce one.

We usually have stock, but the 20 days or so for larger custom orders can stretch depending on packaing. The OEM stuff is where we see most of margin anyway.

It's not suited for rough play or any moisture exposure, the pieces will warp.
Those certificates mean the set meets EU, UK, and US safety standards for children's toys. You get proof that the ABS material is non-toxic and the blocks are safe for ages 8 and up.
It's 3 pieces per design total, not per color. You can mix colors or stick with one—just hit that 3-piece minimum for each model you order.
Yes, you can choose color box, carton, or OPP bag packaging. Just let us know which option you prefer when you place the order.
For OEM orders, expect around 15-20 days after design approval. That covers mold adjustments, production, and packing for the Notre Dame set.
The spec says 'as picture show'—we don't list a fixed piece count because it can vary slightly per batch. Contact us for the exact count on your order.
