This set doesn't include any metal parts nor stickers. You can find more information on LEGO bricks in water here: LEGO.build/BricksWaterproof. - Luigi, LEGO® Customer Service **Q: Ordered this item to gift before xmas! It was delivered to the wrong state. Who do I need to contact for this to be corrected?** A: Hi there! We're sorry for the frustration. In cases like this, it is best to reach out to the seller directly to report the issue with your order. - Sonia, LEGO® Customer Service **Q: Can this actually be played with under water?** A: Hi there! Our bricks are A-Okay underwater as long keep in mind some basic care tips. For example, make sure to have them in plain water - water that has chemicals in it (like pools) might not be good for the bricks. You'll also want to make sure the water isn't too hot, as that can make the plastic change shape. Lastly, always dry your bricks with a cloth, or let them air dry. Don't put them in driers or dry them with heat. - Emily, LEGO® Customer Service **Q: I’m guessing that, since this is lego, there are actually no metal parts and can be taken underwater. am i correct in assuming this?** A: Hi there! LEGO® bricks are A-Okay in plain water. You'll want to make sure that the water doesn't contain any harsh chemicals or cleaners, though (chlorinated pools, for example). And also make sure you let your bricks air-dry - no hot dryers as the temperature can make bricks change their shape. Lastly, while this set doesn't have stickers, if you want to use a set that does have them in water, it's a good idea to leave the stickers off.
