Glass Dropper Decorated - We offer silk screen print to include private brand label and/or graduation marks.  We use an organic ink that will not contaminate any product that comes in contact with our glass droppers.

• These lead-free enamels are recommended for decoration of cosmetic and perfume containers and do not contain voluntary additions of heavy metals – Pb, Cd, Hg or CrVI.

Glass Dropper Packaging - Our bulk packaging is UPS shippable. Each bulk box is lined with a poly-liner to keep the glass droppers corrugated and particulate free. The poly-liners can be removed from the shipping containers and placed in a clear room avoiding corrugated dust from contaminating the environment. Our glass droppers are durable and can be hopper fed into any automatic capping machine.

Upon request - Glass Dynamics, LLC can package your order with glass droppers aligned parallel for a more disciplined application. You must specify this when ordering.
