This set of 2 Gas/Fuel barrels contain custom made pieces. The lids come off, sometimes they are snug enough to remove with a fingernail, sometimes they come out easily when turned upside down. So far my buyers use these for corresponding train setups, but they would be handy for small item storage, or hiding money etc. If you would like custom colors like red, orange, yellow green, blue, purple, white or black please contact me and let me know. The print time for this set is about 2 hours, and depending on how many other orders are in line, custom orders might take just a bit longer to fill but no more than one week. Since these are printed on a 3D printer, there might be a few very minor visual defects. Feel free to ask questions. I do offer returns within 30 days if you are not satisfied. This item is from a smoke free/pet free home. If you have any concerns upon arrival, please contact me before leaving feedback so that I can take care of the problem first. Thank you for reading my ad and have a great day!
