510 Central 100mL LDPE Plastic Thin Tip Dropper Bottles (12 Pack, Multi Color Caps)

These are impossible to use . The outer cap will not separate from the inner drip portion once the inner drip portion is inserted and I put the outer color protective cap on it. These are useless to me.

I use for my e-juice. Works well for me.

Great little bottles easy to feel top easy to pop back off to feel again
