These Customizable Lids are black, concentrate container lids with screw top child resistant locking mechanisms. The flat top is perfect for branding, while the ridged edges are great for increased grip when using. Add your logo on the top of the lids in one color. When matched with our 5ml glass concentrate containers (sold separately), these are a savvy choice for packaging extracts. The thick, quality glass and lined CR cap make this cap/container combo one of our most popular. There are 504 Lids per case.
