Fill Funnel (10-Pack) for Needle Dispenser Bottles

Fill your bottles more easily Fill Funnel (10-Pack) This small funnel makes it possible to fill our 15 ml and 1/2 oz Needle Dispenser Bottles more easily without spilling. Here is a tip to make it easier to use the funnels: Insert the needle of the bottle's cap into the opening of the bottle, and then place the funnel into the opening. This creates a gap that allows air to escape from the bottle as it fills with fluid so the fluid drains out of the funnel instead of backing up and overflowing.
