Excellent condition Quadrilla / Quadrilla's largest set, the Extreme Builder Set, from Bornelund. Plus, a Basic Set is included as a bonus. Many additional parts. There are 157 pieces + 30 or more pieces = 187 or more pieces. This is the largest set in this series, the Extreme Builder Set, and is now discontinued. It includes two extra-large parts that are not found in other sets. The original box is also in beautiful condition. All the parts are present, but the instruction manual is from the Basic Set. Assembly examples are printed on the box. You may also be able to download it from the internet, but I haven't confirmed this. If you would like the twist instructions, I can print them and include them. The original price of this largest set was around 29,800 yen. Furthermore, I will include some parts from the Basic Set. Of course, they are compatible. Most of the parts are there, but there is no box. Also, please share the marbles. This is also in very good condition with little use. Excellent condition. - Brand: Quadrilla / Quadrilla / handled by Bornelund - Product Name: Extreme Builder Set + Basic Set (partial) - Target age: 3 years and up Thank you for looking.
