Great product from a great company
I haven't used any other bubble mailers, but I haven't had to try any other type than what I bought through Royal Mailers. I used to live near their warehouse and could just pick them up when I needed them, but I moved hundreds of miles away. Without realizing, I ran out of stock, but needed to mail books immediately. Royal Mailers had a box of these bags at my door the next morning.As for the bags themselves, I've had zero complains from customers as far as product damage goes. I don't need any more proof than that. Good product, good company, highly recommended.
