40pcs Magnetic Building Blocks 20mm STEM Cube Set

Stock one SKU that covers stacking, connecting and open-ended 3D building: the 40pcs Magnetic Building Blocks 20mm STEM Cube Set (SKU CHT-341104) puts forty plastic cubes in a single iron box, so importers and distributors can list one compact, shelf-ready educational toy across a wide age band.

• One set, many builds. Forty 20mm plastic cubes click together with a satisfying snap, letting children stack towers, link shapes and rearrange open-ended 3D designs — repeat play without extra pieces.
• Hands-on STEM and Montessori-style exploration. The cubes support tactile, self-directed building that fits the educational toy aisle rather than a single-occasion novelty.
• Colour that sells from the shelf. Colourful cubes give the set immediate display appeal in a boxed educational range.
• Age range that widens your buyer base. Listed for 5 to 7 years, 8 to 13 years, 14 years up and 60 years & up — unisex, so it suits family, classroom and hobby buyers in one listing.
• Tidy storage between builds. The set packs into a single iron box, keeping loose cubes contained for retail display and repeat use.
• Compact case pack for wholesale handling. Packed as a single item, with 40 pcs per MOQ — straightforward to slot into an educational toy assortment.
