Mask Round Elastic - 6m Set of 6 Approximately 2x stretch Soft, round type that is gentle on the ears *This elastic is for non-woven fabric masks, so it may stretch out with washing or repeated use. This is a long-term storage item. Although it is new and unused, I opened one to check the elastic. It stretches and shrinks, but it doesn't return to its original length very well after being stretched. Please purchase only if you understand this. Original price: 1650 yen
