Chemistry expert to answer a quick question

Hello, I have a question that should be easy for a chemistry expert:

Is it required to store potassium cyanide at -20 °C temperature? I want to buy KCN but this vendor https://ibb.co/nLKR4tM requires that you store it at -20 °C . What if it's stored at room temperature instead, would the product be damaged? Thank You.
