Large C4 envelopes, although they cost more to send, stand head and shoulders above everything else on the doormat. They also give you the space to tell a story that grabs the recipient's attention and engages them before they've even opened it.
This story is fictional – but at the same time it is representative of what thousands of dogs go through when they are used in research. There are no sensational descriptions of gory procedures here, just a poignant story which tells of one dog's experience. This beat the control pack by 100%.
