Thank you for viewing! These are super cute, fluffy long-tailed tit masks ♥ The front fabric is 100% cotton tenugui, and the lining is double gauze. The double gauze will be either off-white or white, at random. Please be aware of this. Approximately 2.5-3mm thick, 25-30cm long elastic is threaded through without being tied, so please adjust and tie it, then tuck it into the opening.
