ok so yeah, nevermind my last post, I found some at my hardware store, but answer me this. My box is gonna be 20-24 feet long, but those planks only come in around 3 feet lenght. is it worth it to have plenty one to eachother or is it gonna shake from plank to plank, and also, I wanna know how to drill them, cauz it's too thin to drill from underneath (it's about 1/2cm), and so my edges don't catch over the drill holes. I know I'm being a bitch about this, but I don't wanna spend 120$ and regret it. thanks
