The 16 stud by 32 stud Lego(R) Baseplate is part 3857pb01 and has a flat bottom so it can light flat on a hard surface. It was released in the following set:

540 - Swiss Villa

Our baseplates are sold as pre-owned baseplates, however, they are in good condition with no visible flaws unless otherwise mentioned. The only flaws our pre-owned baseplates usually show are micro-scratches on the bottoms of the baseplates. We wash our baseplates in a dishwasher and when they dry, water spots may show on them but they can be wiped off. 

If you are looking for any baseplates that you do not see on our website, call the store at 470-414-2208 and see what we have in stock!
