This item was purchased at Thank You Mart. I tried it on a plushie once at home and then immediately put it back in the bag for storage. Approximate head size for plushies: Approximately 6.5 x 6.5 cm, up to 5cm in depth. I have discarded the original packaging, so I will send it in an OPP bag via standard mail. ⚠️Please refrain from purchasing if you are concerned, as the item has been opened and tried on once.
