very good quality useful extras [SEP] i am very pleased with these glass bottles the glass is thick and while it is certainly not immune to breaking it can deal with the occasional bump without a problem having it be tinted brown is great for limiting the amount of uv that can enter plus gives it a nice look the caps are excellent and provide a good seal the sprayers are just ok they work but are not all that heavy duty i am using these more for storage than application so i am more interested in the cap seal than the sprayerit also comes with a very useful funnel a dropper and a white marker the funnel is something that i will use often i will not use the others but it is a nice complement of accessoriesthe bottles come very well packaged with two layers of bubble pack and are in a box that is the right size to prevent things from moving around they arrived in perfect shape even though they were shipped in a non padded ship bagvery pleased with the set stars
