Oh how I wish I knew about the Korable Block during my years in Korea. I learned how to read and write Hangul pretty early into my time there, but this could have sped up the process. The Korean learning tool was created by New York City designer Si-Yeon Min and contains four wooden blocks hand-printed with letters from the Korean alphabet. Combined, the blocks can make over 120 single-syllable Korean words.
