Colour-Coded Marble Tracing Letters

This set comprises 26 separate lowercase letter boards, each measuring 10 cm × 10 cm and weighing around 45 g. They are crafted from impact-resistant lightweight plastic, ensuring long-term groove integrity and resistance to bending or cracking. Every board displays a single lowercase letter with a dedicated, smoothly routed track sized for a 1.5 cm marble. Colour coding is applied consistently per letter to reinforce visual association and recall. Designed for repeated handling, the material and construction support daily use across varied environments — including home, preschool, therapy sessions, or holiday learning — without loss of functionality or clarity.
