I love these cards. They are nice and thick and have a hole already punched in them for you, so I write sight words on them, put them on a ring, and give them to my daughter for sight word review. Only one word of warning. depending on the type of pen you are using to write on these cards, you might have to give the card time to dry or it will smear. The cards are a matte finish but we did find a particular major name brand marker just did not work well on these so test a card before using a large amount so you don't waste a lot of the cards. They are the perfect size for little hands and for popping them into reading book bags. The rings are included which help to keep the cards together and the different colors help me sort them for different word lists.
