This 32” BEST lightweight stretcher bar is made from high quality and sustainable white pine wood. White pine is plentiful in thin strips of wood, which is why these stretcher bars are priced so affordably, but they are also very durable and will last for several years with care. A great choice for experienced artists who need quality stretcher bars that won’t break their budget. Also perfect for classroom instruction, education, and for new artists. These stretcher bars are cut 1/8” shorter than the listed measurement so that the canvas can fit inside of a picture frame if this is needed.
