Hold-on Pot Holders 2-Piece Set. Modern material, modern design: Søren Refsgaard has created two special coasters for the Danish brand Rig Tig by Stelton that not only allow for the safe handling of hot pots and pans but also serve 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 in the 2-piece set from Rig Tig by Stelton always look appealing, as they can be quickly cleaned with a little water, unlike traditional versions, making them ready for the next use.
