This floating "Boat Life" keychain is a waterproof cube that can withstand being dropped or set on. It has a thickness of 2mm on the walls to ensure its durability and robustness. Across the cube are slanted walls that help with an even print from bottom to top, gradually closing the top hole that would otherwise be too wide.
The key ring can keep an average sized padlock from sinking, which is more than most people's keys weigh. The key ring can also be customized with a text or logo of your choice on the sides.
