An 18-piece rectangle-focused expansion set from Connetix, a premium Australian magnetic-tile brand. Includes 6 short, 6 medium, and 6 long rectangles in vibrant rainbow colors (red, orange, yellow, green, blue, purple). Tiles feature Connetix's signature beveled design for clear light refraction and strong, sealed magnets. Made from non-toxic ABS plastic (BPA/Phthalate-free), ultrasonically sealed and riveted for durability. Recommended ages 3–100; compatible with the full Connetix range and most other leading magnetic-tile brands. Best suited as an add-on to an existing Connetix set to enable taller, more complex builds (ball runs, ramps, towers, carparks). A premium choice for parents who prioritize magnet strength and aesthetic appeal over piece count per dollar.
