Printed it beautifully, but not sturdy

We ordered a small batch of 10 to see if these could substitute for our present vendor. We require large maintenance that are thick and sturdy and lux. These are beautifully printed, but they are not thick enough and they do not appear sturdy and lux imagine very thick pieces of cardboard that stick to fridges and you would not be wrong. Once they are situated on a refrigerator, they look great, but they are hardly something. A customer is going to be thrilled about buying an individual item. I can see they would be great giveaways as part of the marketing promo.
