At last, ｛the caps need to be glued on ｝after you put the material inside (For the glue---you can buy a clear glue which can stick glass & metal from your local hardware store or supermarket , I am always use "Duco Cement","A&B glue".)
There is a about 2.5mm hole on the top of the cap for filling ,you can open or close it by the screw cap !
Like the item but having a hard time gluing the cap on even bought an expensive glu for all types of surfaces. I did not see the part about the lids needing to be glued on or I probably would not have purchased them for essential oil use because if the cap pops off undiluted oils could spill on bare skin. Besides that they are great little containers. Thank you.
