Köpük Topu Pro Yedek Kapağı

This cap is great. Now I am able to store excess formula in my spare bottle for use later. I don't like to leave formula to dry and possibly clog up the internals of the cannon. Storing them in and extra bottle with a cap that seals perfectly is the answer. Great job MJJC for making these storage caps.

Caps are great for storing my foam cannon bottles that have leftover product in them. This way the store produce will not degrade the pickup tube in my cannon.

How the caps on spare bottles are allowed to be so useless, when the main foam gun cap is so great, is beyond me.
The extra caps LEAK no matter how hard you tighten them since there is no included rubber or silicone gasket/o-ring.
Is the one star warranted? Well - It's a cap. It has one job, and it fails at it.
Useless design flaw!

It's a cap

Horrible company. Ship times are crazy long with no communication to the customer the products are coming from china. If you want to wait several weeks for your product this is the horrible company you want.
