Received in 2017, and my two children occasionally played with these. The original box is dirty, so I'm only selling the building blocks. There are shapes like circles, triangles, and squares, allowing infants to touch and learn shapes. Also, being made of cork, they seem safe to play with even if they are stacked high and collapse. Alcohol-sterilized! Out of a total of 19 pieces, due to the cork material, there are chips on the corners and edges of 6 pieces (see photo 3. The corner facing the center is chipped). It's not very noticeable in the photos, and I think it won't significantly affect play, but I'm listing them as "slightly scratched or dirty" because of this. Photo 2 shows all the blocks flipped over. I have guinea pigs, but I store these in a separate room. Please understand that these are amateur-inspected and stored. Feel free to ask any questions! A set of 15 cork educational building blocks. - Shapes: Cubes, cylinders, triangles, rectangles, semi-circles - Material: Cork - Quantity: 15 total - Uses: Educational, building blocks, shape recognition - Color: Beige Thank you for looking. #CorkBuildingBlocks #EducationalBuildingBlocks
