Question: How long is the chain, from the plug to the boat?
Document: My two little boys were so excited to receive these in the mail.The plug was smaller than what worked in our bathtub, but that didn't matter. We disconnected the chain from the hook on the side of the boat and just used the boats to play/not plug.The boats are a nice bright color and have been a fun addition to bath time.
This item worked perfect for a commemorative Christmas ornament for my son who was really into the Titanic this past year. I just unhooked the chain and plug and used an ornament hook.
This ship bath tub plug works great. The toy boat floats. Well half way floats. LOL!1 5/8 to 1 3/4 plug size. It does not say the size on it or on the package it came in.I got the size information from another bath plug I had.I'm gonna have fun with this. Yeah!
The boat is good quality as is the plug. The plug works well and fits the drain in the tub well. The only issue I have is the cost of shipping and the length of time it takes to ship. I bought it as a gift for a child but it came too late for the birthday. If I pay that much for shipping (almost as much as the boat itself) I at least want it to arrive very quickly.
I have looked high and low for a Titanic TOY for my 4 year old who is obsessed with Titanic with no luck until now. Since there are no actual Titanic toys available anywhere this bath plug is the PERFECT substitute. We mainly have the chain unhooked from the ship since my 4 year old carries it everywhere with him. He even takes it to bed. If you have a child who is obsessed with Titanic then this is a MUST buy. Your kid will LOVE IT!
This is a well made item, and fun for a child to play with. The boat is also easily detachable. My grandson loves it!
Very cute. I took off the plastic loop & connected to the metal one & my son loves it. We do not pull the boat, of course, to get it out we pull by the black stopper.
This was a late Christmas gift for my nephew, and he loves it. I had to add a few links to the chain so he could fill the bath as full as he wanted, but otherwise, it's great.
It is so hard to find a titanic toy for kids! This is small and cute, wish it was a little bigger, but my 4 year old loves it. I easily took the chain off and we use it as a toy. Seller shipped it faster than the estimate, we got it within a week not a month that was estimated.
This is what was promised and my grandsons love it. If the plug isn't right size it is easily interchangeable.
Answer: 13 inches
