Yes we can make these available. I had these custom made for me. No real supplier on the net for them. I had to order 1000 of each size. I have 2 sizes depending on which phone you want to mod. These will be $5 a pair for either size. let me know which phone and I will tell you which works best. Another handy tool to have is a glue gun so you can put a little dab of glue behind it to keep it from spinning etc. As the every phone enclosure has a different wall thickness we could not make 20 different sizes, thus we use the hot glue where the wall thickness is smaller than the gap on the strain relief.
Thank You.
