These are double loop straps for use with a Pilates reformer. Most straps are black, so these will brighten up your reformer considerably. (No brand) It's also a good idea to have your own for group lessons, etc. The outer fabric is canvas, and the back is fleece. I've included photos of the dimensions (taken with a smartphone while holding a measuring tape, so they may be slightly off). The side-by-side photo shows the back and front. Other colors are available for this product. Please refer to the last photo. Shipping will be via Nekopos with simple wrapping.
