What exactly are they?
FlashSticks are essentially flash cards, but presented as Post-It notes. They contain the word in the target language, plus the pronunciation, gender of the word (also shown by the colour of Post-it note) and type of word (e.g. noun, verb). There is also a related app. I received the French beginner pack, but this product is also available in Spanish, Italian, German, Portuguese, Mandarin, English and British Sign Language.
