The luminescent pigments in IHFAIO's mini resin animals are designed to absorb ambient light and emit a soft glow. While specific duration isn't quantified, typical phosphorescent materials can glow for 2-8 hours after a sufficient 'charge' period of at least 30 minutes under direct light sources like sunlight or a bright lamp. The intensity will gradually diminish over this period, providing a subtle ambiance rather than bright illumination in complete darkness.

Crafted from sturdy resin, these IHFAIO miniatures offer reasonable durability for decorative purposes. Resin is generally resistant to minor impacts and moisture. However, prolonged exposure to harsh UV rays (direct sunlight for over 500 hours) can lead to color fading or surface degradation, and extreme temperature fluctuations might cause brittleness. For optimal longevity, placing them in shaded areas or protecting them from direct weather elements is recommended.

The IHFAIO set offers 100 pieces across 15 distinct designs, including ducks, unicorns, and cats. While the exact distribution per design is not specified, bulk assortments of this nature typically aim for a reasonably even spread to provide variety. Users can expect multiple pieces of popular designs and at least a few of each unique figurine, facilitating diverse DIY projects or collection building.

These IHFAIO miniatures are carefully crafted in 'mini size,' ideal for detailed arrangements. While specific dimensions for each animal are not provided, their compact nature, typically ranging from 1-3 cm, makes them well-suited for dollhouse scenes or terrariums where space is a consideration. Their detailed sculpting allows for visual appeal in close-up displays, though exact scale comparison to specific dollhouse furniture would require individual measurement.
