excellent quality useful accessories good protection [SEP] i am impressed with how well these glass bottles are packaged by the manufacturer each bottle is double packed in bubble pack and all accessories are wrapped up so they cannot move around and damage the glass bottles even though the shipping box was beat up the bottles were all finethe glass is of good quality in terms of thickness and quite sturdy as far as glass can be however the brown tinting is excellent for uv protection of the contents the accessories are mostly useful items with the best ones being the caps and the funnel the caps have an insert to provide an excellent seal which is key to maintaining content freshness they also come with spray heads that while functional are rather lightweight in terms of build qualityall in all an excellent set of bottles that are packaged very well and come with some very useful extras very pleased
