These blocks were used by a child. They're similar to LEGO, but not LEGO. Most of them have "Fy" written on them, but some don't. I used to carry them around when we went out, in case my child got fussy. I chose these instead of LEGO so it wouldn't matter if they got lost. There are some minor scratches, but please understand that these are used items and purchase them after confirming the images. Thank you.
