Please reach out if you have any questions or if you would like customization. *PLA is a hard bio-plastic obtained from renewable resources and natural raw materials such as fermented plant starch from corn, cassava, maize, sugar cane or sugar beet. It is intended for indoor use and can only be hand washed with lukewarm water and soap as it cannot handle high heat. Care instructions: Many items are 3D printed using fused deposition modeling fabrication (FDM). One of the materials used is PLA which cannot handle high heat and is intended for indoor use. For PLA, hand-wash only in lukewarm water, use a mild dish soap, do not wash in dishwasher or use heat to dry. For ABS, it is heat resistant up to 212°F (100°C) but will be damaged by extended UV exposure. Lines and marks on the item: 3D printing carefully lays material line by line to form layers; these lines need to start and end, which causes a mark and is part of the normal process. It's similar to a fabric art, where there's a beautiful front and a back where the seams and contour lines show. Each 3D printed part is unique and made to order which will result in no two items being exactly the same.
