Tupalizy 120PCS Bra Strap Hooks for Sewing Bikini Halter Swimsuit Tops Lingerie Rings Metal Bathing Suit Clips Clasp Adjustment Slider for Slip Dress, 3 Styles, 8mm and 12mm, Silver and Metallic Black

Perfect size for sundress straps, bra straps, etc. will hold up cause they are metal and well made. I have taken all my sundresses that had the plastic strap adjustment sliders on them and replaced them with these metal ones. As u can see there is two different sizes of all three. To give u an idea, The smaller “double o” slider (ones on the top left in pic) is the right size for a bra strap and the bigger “double o” (bottom left) slider is perfect for sundress straps.

Useful indeed i repaired a lot of my clothing items with these

Had to return, my mistake it's too small.

I cannot speak to how these will hold up to washing, but they are good quality metal out of the box.

Purchased this for sewing products. Works as designed. Glad I purchased it.

Lots of choices. Just not what I was hoping for.

Good quality and good value.

My daughter’s swimsuit broke. I found these which were identical to the broken piece and ordered them. In about 15 min I had the broken one out and the new one installed. Very happy with them! I also have extras if this happens again.
