What idea to send food with cleaning products !!! The post office had to repackage the packet, which has not prevented the bottle from sinking. I read in the comments of household products that other buyers have had the same problems but I thought that Amazon had resolved that ... But I admit that the Amazon customer service was efficient again and replaced all damaged items within 48 hours (faster than the 1st order)! Apart from this misadventure Sanytol the product is very effective.
