For a 10cm size with a head circumference of 18.5cm, the beret will be a little large. Please adjust it with safety pins or similar. If you comment that you need a brooch pin, I will include a small 1.5cm brooch pin. Please see the example photos for how it looks. Craft glue is also used, so glue marks may remain. Velcro is attached with glue. It may come off if stress is applied. If it comes off, please reattach it with glue. This is a handmade item by an amateur, so please refrain from purchasing if you are looking for a perfect product. There is a possibility that it may not fit depending on the shape of the plushie. Please understand this before purchasing. The plushie is not included.
