The company on taobao.com that I bought my flashcards from has recently introduced this new product, and I decided to give it a try.
It comes in a nice box, with foam padding on the insides.
There are three packs of 50 cards each. Each set of 10 cards follows a general theme (for example, colours, shapes, animals, body parts). The cards are made of durable paper that is slightly water resistant, so I did not consider laminating the cards to lengthen their lifespan.
I think the cards are quite well made, the pictures are nice and unambiguous, and there are no distracting background images. These cards can be used for linking memory games and even clairvoyance/telepathy games. There is an instruction booklet within the box that gives you a few suggestions on how to use these cards.
The cards cost me $28.50 inclusive of shipping. An ok buy if you want to introduce some variety into your Shichida home practice materials. If you are on a tight budget, you may want to consider buying playing cards like ‘donkey’, ‘snap’, ‘happy family’ and ‘old maid’ from old neighbourhood shops that can serve the same purpose as well (each pack costs less than a dollar).
