This is my third order for Vulkem sealant. The first arrived undamaged in the usual Prime Box packaging. The 2nd and 3rd orders arrived in a paper envelope (2nd) and a plastic envelope (3rd). Both later deliveries had damaged tube ends as shown in the picture above. One seemed unusable and went back. I had to pay a 10% price increase for a replacement tube which also arrived damaged but still usable (plastic mailing envelope). I don't know who in Quality Assurance decided that cheaper packaging would be appropriate for this type of product, but I will not purchase this or any other sealed product until they are told they will ship in boxes. I will be going back to the local shops for shopping regardless of the price. Buyer warning!
