TXIN 100 Pieces 5mm Elastic Ropes String Stretchy Stretch Elastic Cords, High Elasticity Elastic Strap Adjustable Buckles Band Ear Cord for Sewing DIY Craft Clothing, White & Black

Only received 91 out of the 100 pieces. 42 black and 49 white.

These are exactly what I needed to make masks. They are soft and comfortable on your ears, and easy to adjust. It’s hard to guess the exact size people need if you can’t measure in person, so these are a perfect solution. I was nervous about the length when I ordered, but they have plenty of stretch and have fit everyone I’ve sent masks to. I have washed them several times (in mesh bags) with good results. I was so happy that I reordered more.

I'm using this elastic on my masks I'm making. I thought the pre-cut elastic with adjusters would be helpful. I am concerned the elastic is not good quality and will deteriorate with time and customers will be returning to me unhappy. Also, they were cut to all different lengths so I always have to trim them up and even them out before I sew them onto a mask. I'm a bit disappointed with this product but since I have used some of them feel I can not return them.

As others have said - these are great, unfortunately you don’t get 100. I was splitting the quantity with a friend and so I had to count as I divided the quantity up. Sure enough. There is not 100. Less for both colors. Very disappointing. Luckily I had bought a package from another seller so I had enough to cover the missing amount. If you need exactly 25 pairs of either color then buy an extra set or take a chance on another seller.

i love the soft feel and the size of them even though they are adjustable. Great product would order again.

I really wanted an adjustable band for making masks, especially so that my kids would have a good fit on their mask. This works really well. If you happen to pull to hard and pop off the adjuster, you can just attach a safety pin to the fabric and pull it through the adjuster. The adjuster has some give to it, so a small safety pin can be pushed through.

These are so good for using in making masks! Being adjustable really makes for a better mask fit. These are soft and the plastic button used for the adjustment is a soft plastic as well. It was nice to have both the white and black for the fabrics I have been using.

My son is excited for me to use these for new masks for him. I made masks without an adjustable earpiece and they are "too small". Having the option to adjust will make all of the work to make masks worth it, so my kids will wear them. Elastic is stretchy and soft. If the plastic adjuster were to come off, there is basically no way to get it back on, so just don't pull them off. I didn't make an effort to count the straps as I won't make anything near 50 masks anyway.
