The Poppy and November 11th

The Poppy Campaign by the Royal Canadian Legion is something I have always supported. But why have they designed this poppy in such a way that you can guarantee it will fall out at the slightest provocation. I would prefer to pay $5 for a poppy that stayed than $1 for one that falls out. I guess they are worried that they will have a significant drop in revenue if they solve the problem - I doubt it.
