【Detailed Information】 This is a gypsum tooth model of natural teeth. 【Uses】 Useful for professional dental model creation, art projects, etc. 【Condition】 Visually, I don't think there are any noticeable large air bubbles in the abutment teeth or margin areas, but I did use vacuum mixing, so please understand if there are small air bubbles. I'm using brown, extra-hard gypsum. All parts are in good condition and suitable for use, but please consider only if you are not concerned about minor details. Thank you. Thank you for viewing.
