Once you have purchased the products in the form of a pre-prepared package, you can return only the entire package and not the individual products in it. It is also not possible to return products, which are quickly perishable or have a short shelf life or products that have been manufactured according to your instructions or are personally tailored to you and products which, because of their nature, are not suitable for returning, as they are inextricably mixed  with other objects. It is not possible to withdraw from the contract in respect of other groups of products which are defined in the Consumer Protection Act.
