Update- I did get another pair of these in size 6 and they fit like my Birks, so Im pleased. Comes with Teflon tape. The lighting is BEAUTIFUL! They are so comfy that they can be worn all day long. First - a quick summary. 0 which has much better range. Super bien magnífico agarre en lo mojado se secan muy rápido y son muy cómodos Ive also begun using them on frequent Zoom calls on my computer and tablet. If hanging a girl bike I would recommend. It reminds me Iriver mp3.
