I bought one each of the Side Winder Mini and Side Winder Max cable spools. The mini is just large enough to wrap up a braided lightning cable while holding the connector ends in place. The larger Max was purchased to hold my precious In-Ear-Monitor headphone cable securely in place with a mini-headphone jack to Lightning Cable adapter attached to the far end. The plastic material is soft enough to deform to slide a cable end in place, but firm enough to securely hold it when in storage. I also appreciate that the finish is subdued and not covered by flashy graphics.
I just love it!
