To use the condiment gun, just fill up one of the two canisters with ketchup, mustard, ranch, or whatever condiment you prefer, load it into the gun, and just squeeze the trigger to slowly dispense your sauce.
When you pull the trigger a tab gets pushed onto the back of the sauce canister and it squeezes the back to squeeze out the sauce. It doesn't require any batteries or power to use, as it's completely powered by you squeezing the trigger.
The condiment gun comes with two canisters, one with a yellow cap, and one with a red cap, each for your ketchup and mustard. But you can really put any kind of condiment inside the containers for use with the condiment gun.
The condiment gun works with ketchup, mustard, BBQ sauce, mayonnaise, ranch dressing, and really any other sauce you need to dispense onto your food in the most awesome way ever. The ketchup gun is made from plastic, is suitable for kids aged 12 and up, is red and yellow in color, and measures 8.8 inches long x 6.1 inches tall x 2.1 inches wide.
