Ultimate Builders Set (set 3800-1) is an extremely old and rare LEGO set. It has not been seen for sale online or in retail stores in good/new condition in over 2 years. Due to its rarity, the current estimated value of $698.63 may be much lower than its true value, assuming it can be found for sale. As this set was released in 2001, finding it sealed and in good condition is particularly challenging, likely driving its true value even higher.
There are currently no new/sealed listings available for Ultimate Builders Set at this time.
