Judging by their returns policy, they seem easy enough to box.

What Item(s) are you looking to SE?

I was looking to do a pair of balenciaga trainers for £500, they only weigh about 250 grams

There's a few methods that can be used.

* Boxing- 250 grams Is not a significant weight and with some extra packing ("solid" cardboard and not perforated), the weight will almost match.
* Wrong Item received- get a significantly cheaper "stock" Item and upon their request to return It, send that.
* DNA- obviously.

Bear In mind, some carriers tend to round up the weight to the nearest decimal/Integer, so the weight on consignment may not be a true representation of It's contents. This Is beneficial when boxing and also the empty box method when the buyer receives the package.
