What is Lego Set?

Why are Lego Sets So Expensive?

  • Attention To Detail

LEGO is known for its precision engineering and attention to detail. Each mold is precise; it is accurate within 0.004 mm, which is ten times narrower than a single human hair. Each LEGO brick has three numbers that indicate the mold’s position and which mold was used to produce it. With the numbering system, a faulty mold is quickly discovered and fixed. 

  • Brand Building

Receiving LEGOS as a gift is not just getting another toy; it is an adventurous and delightful experience, with educational value, that keeps kids entertained for hours. LEGO is probably the favorite toy brand in the world for many kids…and adults too.

  • High-Quality Material

LEGO is made from thermoplastic, which is known for its strength and durability. The specific plastic, acrylonitrile butadiene styrene, is a petroleum product. It means the raw material pricing is related to the price increase or decrease of crude oil.

  • Size of LEGO Sets

The number of pieces in a LEGO set influences the cost and, therefore, the price you pay. 

  • Resale Value

LEGO does not lose its value as a secondhand toy. It may even increase in price.
