If you love Princess Peach from Super Mario, you will love this Crown headband which fits SmartDoll /DD perfectly.
Please noted that the Crown Headband is 3D printed in extremely high quality white resin (from formlabs.com) with 0.05mm resolution, which takes us 8 hours to print one, and post processing for 30 mins for each headband.
However, it is not plastic molded. Meaning, it will NOT be smooth, but it serves well for photography purpose.
(If you are looking for nicely finished product, wedo notrecommend you to get this headband)
