My child used these, but is no longer using them, so I am selling them. They have suction cups, so they were very useful in preventing the plate from being flipped over. They are dishwasher safe, making them easy to clean. There may be some minor scratches from use, but they are in relatively clean condition. This is a set of two. How about for twins or siblings close in age? The following is a product description: 【Safe and spill-proof with suction cups that stick.】 The plates and bowls with suction cups are fixed to the table, so you can eat without flipping them over. 【Unique design perfect for practicing eating on your own.】 Deep plates that are easy to scoop with a spoon. Designed to be 3.5cm deep, deeper than typical baby dishes, to help children practice eating on their own. Also, the front of the plate is designed with a straight cut to minimize spills by bringing it closer to the body. 【Easy to clean with silicone material.】 Heat resistance: -20 degrees to 220 degrees Celsius. Excellent heat and cold resistance, and compatible with microwave ovens and dishwashers. Silicone material is also durable and can be used for a long time. 【Product Specifications】 Plate: Diameter approx. 20cm, Short side diameter: approx. 18.5cm, Depth: approx. 3.5cm Type: Plate/Dish
