Review title is Bad quality control! [SEP] When the first order is made, the sponge head is easy to fall off, but the sponge is in good quality. I ordered it again since it was easy to remove mucus, but the quality of the sponge is getting rough. Now, the quality of the sponge is not only rough, but also the glue not evenly on the stick.  it was like a ball on the top portion of the stick. It"s hurting patient's mouth and very uncomfortable to use them. I throw many away and will not order again!
