Due to time constraints we have discontinued color options on our glass tubes for the foreseeable future. please do not contact us to ask when/if we will be bringing color back as we simply do not know at this time.
We will continue to provide clear glass products and try to get everything streamlined to better expedite your orders. We know for the last few months some of your orders have taken much longer to get out than we would like and this change will help us to serve our customers better.
Our Glass tubes are Borosilicate (many know as Pyrex) and are precision ground to close tolerance. Along with our glass tubes our End Caps are made in the USA.
