LEGO 31145 Red Dragon Investment Watchlist
Set Overview
The LEGO Red Dragon (31145) is part of the LEGO Creator 3-in-1 theme, so you could either make a Bird or a Fish, released in January 2024 with an RRP of £8.99. As a lower-priced set with strong fantasy appeal, it has quickly become a popular entry-level purchase and maintains a strong sales rank relative to its price point.

With retirement expected July 2026, the Red Dragon represents the type of small, affordable set that can attract both casual buyers and collectors, particularly due to its display appeal and versatility within the Creator range.
Historic Price Behaviour
Smaller Creator sets typically see modest discounts during sales periods, and the Red Dragon has followed a similar pattern since release. Sets in this price category often sell in high volumes, particularly as impulse purchases or add-on items during larger LEGO purchases.
Strong sales rank performance suggests consistent demand rather than clearance-driven activity, which is generally a positive sign heading toward retirement.
Investment Thoughts
- Low entry price allows accumulation at minimal risk
- Dragon and fantasy themes historically remain popular
- Display-friendly design despite small size
- Creator 3-in-1 sets appeal to a broad audience
This set is always insanely popular when at full price it’s sales rank for toys and games is 400. When discounted it is often in the top 20.
It continues to sell well when out of stock which is another big advert.
Smaller fantasy-themed sets often perform steadily rather than dramatically after retirement. The dragon subject matter has long-term appeal across age groups, and the affordability of the set increases the likelihood of continued aftermarket demand once retail supply ends.
The primary risk is high production volume, as low-priced Creator sets are typically produced in large numbers. Investment returns are therefore more likely to come from buying at discount and holding over a longer period.
With this being a quite low priced set, we will want a big jump on price after market to see if worth while. As always the best advert is to look at similar sets as see how they have performed.
Comparable Retired Sets
- 31124 Is a 3 in 1 set. A Robot at the same price point. Retired in 2024 december so has had just over a year on the after market. It was also popular (not quite as much as this one) But swiftly went up to £15 and if you wanted to buy it currently you would be paying £20 -25
Amazon Link
31125 Forest creatures was at a slightly higher price point. But as still gone from £12.00 to £25 – the important thing as always is buying at a discount, and you will make money with these 3 in 1 sets
BrickAnalyst Verdict
✅ Buy under: £6.50
⏳ Hold period: 1-2 years post retirement
⚠️ Risk level: Low (The quick sales rank will ensure any under cutter sells clear out early)
This set will definitely make money, whether ts returns comfortably exceed 100% we will have to wait and see, so depends on your individual strategy
