I bought a elastic cord from nbeads in March to make my own mask. Due to the impact of COVID-19, the shipment was affected. I have not received my package for a long time. You need to be patient after communicating with nbeads customer service. I finally received my package in April and made a mask. I'm so happly. Although I waited a long time, the product was very satisfactory. Nbeads gave me a new coupon after I wrote a review.
