I think it was a really great idea to use a cylinder instead of a box. It makes the product stand out and if you designed much smaller ones they would be great for people to keep them in, in a place that is easy to take with you and prevents the risk of them becoming too weak from being carried in a wallet or purse. The only thing I would consider making more clear is what gender you are marketing towards.
Well when i mentioned a lesser contrast its because people generally have some taboos or prejudges in sexual products, so i rather a more friendly colours to sell this one, no need for making a condom elegant since this is for private and "throw-away" use product. Anyway i would use a field investigation before chooose design elements . Greetings to all.
Just a constructive commment: Im a publicist, design looks great but i would use a lesser contrast instead of black background, and concept is nice and clever but i think it not reaches the target unless this is thinking for a female customer.
