This is a sink slide cooking board. It comes with a cutting board plate, making your kitchen convenient! It's an extendable type that fits perfectly in the sink. The cutting board plate is also removable. It's perfect for a compact kitchen, ideal for single-person households. I haven't used it much, and it's in good condition, so it's a shame to just keep it. I'm putting it up for sale. Images 10-12 are reference photos. If anyone would like it, please! The price is almost just the shipping cost.
