Best parcel boxes / protection for Model M

[zippolupan]

For the experienced eBay sellers,

What is your preferred parcel box for shipping Model Ms around? What do you use for protecting the boards? I'm planning on selling a few models I have here on eBay but most boxes I find online are either too small or extremely large/deep and I fear it might cause issues if the keyboard is dancing around during shipping.

Do you have any particular model or ideal dimensions that work for you?

I'm in the UK, for context.

Thanks all!

Newspaper, packing peanuts, airbags or foam between the two.
