⏳ Retired

The LOM Building B set holds good investment potential due to its exclusivity and limited availability. As a LEGO Exclusive released in 2014, it's already retired, increasing its rarity. The low piece count might deter some, but the set's unique design and limited distribution make it attractive to collectors. Its value is expected to steadily appreciate over time, especially among those seeking to complete their collection of exclusive LEGO sets. However, like all investments, there's a risk that demand could fluctuate.
