White Resin Large Rectangle Frame (R7020) (25 ratings) £2.25 SORRY THIS ITEM IS CURRENTLY OUT OF STOCK - PLEASE CHECK BACK AGAIN SOON. 1 per pack 120 x 90mm Flat back. Each piece is handcast from white resin. You can easily change the colours of resin by painting them with gesso, then they can be sprayed with any product, Lindy's is my personal favorite. Paint them and even glitter them. Please allow for slight defects in casting.
