這款 26 點字字母 A-Z 套組可以 2 面遊玩，一面是大寫字母，另一面是小寫字母。每塊積木都有一個點字符號，代表字母表中的每個字母。
The tactile dots are raised just enough to feel clearly under my fingertips, which makes practicing letter recognition with my students actually work. Twenty-six tiles cover the whole alphabet, so we can spell short words once they get the hang of single letters.
The tiles being double-sided is such a smart touch, so my daughter can practice uppercase on one side and flip to lowercase without needing a second set. The Braille dots are raised enough that her fingers catch them easily during practice.
