★ About Materials While we use resin that is resistant to yellowing, it will still degrade over time due to its nature. We hope you enjoy it as a consumable item. There are no noticeable air bubbles or scratches, but due to being handmade, it does not have the same quality as items found in stores. Please refrain from purchasing if you are highly sensitive to imperfections. Furthermore, we consider any air bubbles or imperfections on parts not visible when worn to be non-existent.
