Please understand that all items in my brand, JorTene’ Arts, are hand crafted and handmade items by nature, have imperfections. Although I am very attentive and strive to perfect each piece to the best of my ability, subtle imperfections may still occur. Performance of the product (coasters, trays, tumblers) will in no way be effected. Accepting that there are no two pieces in my shop that are alike, you are aware that you are truly receiving a unique, one of a kind item(s)! As always, thank you for shopping with JorTene’ Arts.
