Great question! I have worked with a few orthopedic doctors and they think its great. They do not believe it will hinder the cast in any way. In the begining phase I wondered that as well, but they felt it wasn`t an issue.
Shrinkins is designed to be changed and reused just for decoration. So it is a temporary product.
I have focused so much on webdesign, product, product styles, packaging, displays, profit & loss, samples & feedback, investors, patent filing... and I can`t remember what else... I havent had a chance to check out large medical manufacturers, to get their interest. It is soo hard to be every department of a new business!! I will check out baxter and medline right now, if you think of some others please let me know.
My closest competition, is Castoo. I found them about 6 months ago. It really upset me... as if I would be the only creative one who would think of this!! :) They are similar that they decorate casts, but theirs is stickers and it can only be used one time. Mine covers and protects new and OLD casts. So if the cast is dirty or written all over, this will make it look like new again- and mine also can be reapplied several times which will allow kids to continuously rotate and reuse their designs. ANYWAY, Castoo just signed an exclusive deal with 3M, I really had not thought of 3M being interested in these types of products...but I guess they are.
So, I guess I need to start checking out manufacturers like them as well. Do you know of other fortune 500 companies involved in the medical industry?
