I’m so satisfied with those poster of many Kanji characters, even though not all of the most common 2,136 characters included, many most of them are! (About 2,114 )
I highly recommend these posters for Kanji learners.
This tool is really wonderful for helping you memorize kanji! I highly recommend giving it a try.
I really like my kanji flash cards! I keep the set I'm studying clipped onto my bag, so they go with me almost everywhere. They're holding up well so far despite not being in their protective case most of the time. And they're super helpful to quickly glance at while I'm on break at work or anywhere else that I have a quick second. Definitely a worthwhile investment for me.
