What the Trexii x NKF blind box actually is
The Trexii x National Kidney Foundation (Singapore) Series Blind Box is a limited-release collectible figure series: six regular styles in total, sold as single blind boxes or as a whole set of six. Each figure is 3 inches tall and made of PVC/ABS.
The series is aimed at adult collectors. The listed age range is 15&Up, so it is not a children's toy line. If you are buying it as a gift, check that the recipient fits that age guidance.

Questions collectors ask before ordering
- How many figures are in the Trexii National Kidney Foundation series?
- The series includes 6 regular styles. A single blind box contains one figure, and the style stays unknown until you open it.
- Can I get a secret or hidden figure?
- Yes, there is a certain chance to win a secret edition among the series, also called special, variant or hidden. If a secret figure is in the box, one basic figure may be replaced randomly.
- What happens if I buy a whole set and get a duplicate?
- The product information states that the whole set contains 6 blind boxes with no repetition. If you buy a whole set and still receive a repeated figure, contact the store and they will try to find a solution. Certain brands such as Bandai, Mighty Jaxx and Kenelephant are excluded from that arrangement, but this Trexii series is not listed among them.
- Is the Trexii limited blind box Singapore release suitable for children?
- The listed age is 15&Up. Treat it as a collector item for teenagers and adults rather than a toy for younger children.
- Will the figure look exactly like the photos?
- The display picture and size are for reference only. Actual product, size and color may differ due to lighting, display screen, photography style and other factors. Measurements can also vary within a standard range of 1 to 3 cm (0.4 to 1.2 inches) because of different measurement methods.
- Does this Trexii charity blind box support a cause?
- The series is a collaboration with the National Kidney Foundation (Singapore), and the product name carries the Limited-NKF label. The supplied product information does not state a donation amount or percentage, so check the listing or contact the store if that detail matters to your purchase.
Single box or whole set: what changes
A single box is the low-commitment way to try the series, but you cannot choose the figure and you may end up with a duplicate if you buy more singles later. A whole set of six is the cleaner route if your goal is the complete regular lineup, since the set is listed as containing 6 blind boxes with no repetition.
Either way, the secret figure is not guaranteed. The chance element applies across the series, and a secret can replace a basic figure in a box.
Before you check out
- Confirm the age fit: The 15&Up listing makes this a collector purchase, not a young child's gift.
- Read the shipping and return policy: The product information asks buyers to read the shipping and return policy before purchasing.
- Expect small measurement and color variation: The 1 to 3 cm (0.4 to 1.2 inches) measurement range and lighting/screen differences are disclosed, so plan display space with a little tolerance.
- Use the collector community: The listing points to a Discord server for launch info, trading and swapping, blind box shake tricks and a monthly giveaway lottery.
