How can I ensure a secure fit between the dropper tip cap and bottle?

     To ensure a secure fit between the dropper tip cap and bottle, there are a few simple steps you can take:

     1. First, make sure that the dropper tip cap is fully seated on the bottle. You should hear a click or snap when it is in place. If it feels loose or wobbly, try pushing down on it again until it's firmly in place.

     2. Check that the threads on the dropper tip cap are clean and undamaged. If there is any debris or damage, it can prevent the cap from fitting snugly on the bottle. Use a soft cloth or brush to clean the threads if necessary.

     3. Make sure the bottle neck is dry before putting on the dropper tip cap. Any moisture can prevent the cap from sealing properly.

     4. Finally, store the bottle upright and avoid jostling or shaking it too vigorously. This will help prevent the dropper tip cap from coming loose or leaking.

     By following these simple steps, you can ensure that your dropper tip cap fits securely on your bottle, giving you peace of mind and ensuring that your products are protected.
