This is an official silicone plate that can be placed on the narrow Beyond Junior high chair. Of course, I think it can also be used on high chairs other than the Beyond Junior. Please check the size in the photos m(_ _)m I used it for about 2 months, but I no longer need it, so I'm selling it. I think it's in relatively good condition. It will be shipped by post. Thank you.
