These are plastic beans that came with a combination pillow. They come in two sizes and are placed in a net to adjust the pillow's height. I prefer low pillows and don't need the beans, so I'm selling them. There are enough for two pillows. The mesh net has a double zipper to prevent the beans from spilling out. One side has Velcro to attach to the pillow itself. I used the beans to lower the pillow once or twice. Therefore, two of the four nets have more beans in them, but I will send them as is. The price is set due to shipping costs. Thank you for your understanding. I hope someone can use these. Please consider purchasing if you understand that these are used items.
