Mini Blank Flash Cards with Binder Ring - 1.25" x 2.5" Set of 4 Decks (320 Cards Total) - Perfect for Study Notes, Language Learning & Classroom Activities

Bought these to study anatomy terms. Love how small they are - makes it easy to carry them around. I can fit a lot of information on each card, but I would not recommend these if you put paragraphs on your flashcards or like to draw pictures - they are a bit too small for that. They are about the same thickness as a standard index card, not super heavy cardstock. The rings are plastic (comes with 4 rings - my picture only shows one set). I'm not sure how they will hold up over time, but for now they seem sturdy enough.
