The UKI Moods & Weather series is a charming and expressive blind‑box collection from 52TOYS, created in collaboration with the artist Hayashi Uki (UKI). Each figure embodies a different meteorological element or mood, turning atmospheric phenomena into adorable character designs.

• Blind box format — each individual box contains one mystery figure (random). 

• Lineup — 8 regular designs + 1 “secret” (rare) type (the “Star”) 

• Probability / Rarity — the secret figure has a lower appearance rate (often cited as 1/96)

• Size — approximately 7 cm (≈ 2.8 in) in height (though some sources mention a small range, e.g. 7‑11 cm) 

• Materials — made of PVC and ABS plastic 

• Age Recommendation — intended for ages 15 and up (due to small parts) 

• Design Theme — manifestations of weather and moods (sunshine, rain, wind, lightning, snow, cloud, moon, etc.)
