The cards are quite handy. They include the N5 and N4 Kanji;s one the front of the cards with some reading of the Kanji in hiragana on the side, On the back is the reading in English with a mnemonic picture to remember the Kanji. There are also some words included that shows the different readings of the kanji. The ring is fantastic and easy to use. It is also large enough to hold the first 100 with ease.
