Hold-on Pot Holders Set of 2. Modern material, modern design: Søren Refsgaard has created two special coasters for the Danish brand Rig Tig by Stelton that serve not only for gripping hot pots and pans but also as pot trivets. The heat-resistant silicone (up to 230°C) is folded using the finest Japanese origami techniques. The folds trap cold, insulating air and enhance grip, ensuring that no hot pot or pan slips through your fingers. The Hold-on pot holders from Rig Tig by Stelton always look attractive, as they can be quickly cleaned with a little water, unlike traditional models, and are ready for the next use.
