Two different options for these book holders: triangle and diamond. These unique book holders have iridescent flakes with sparkly lavender mica powder encapsulated in heat resistant resin. All book holders are made to order and can vary in color and look from the pictures. All are made with high quality resin, mica powders and foils so theyll last.Each piece is handmade meaning slight imperfections are part of their characteristics. Items will be sanded if needed.Bubbles are common in resin and are unavoidable. I do my best to try and minimize them but can still be present.Feel free to send me a message via Faire or Instagram @hold.it.there to discuss any questions in regards to your order.
