White label means basic products of manufacturer, and it can be used by other designer and add some designs on it then make it to their own products.
Main difference of Branded items and white label items is, branded items only can be sold by owner and he can change or improve products by his own wills.
But white label items can not be like that, cuz manufacturers sell those items to multiple traders, then they will re-pack the products with their packagings and sell to customers, without changing anything.
