So these are the ones that I purchased a while back. For some reason, Amazon says they only have used ones? Very weird https://www.amazon.com/Starwood-Sports-Exercise-Resistance-Bands/dp/B016V4JOZA?ref_=fsclp_pl_dp_1 I will say this, though. They are not as thick as I would like them to be. If you’re not a beginner/just getting used to resistance bands, I would highly recommend this type: https://www.amazon.com/Perform-Better-Exercise-Mini-Band/dp/B01GVS9EQK/ref=asc_df_B01GVS9EQK/?tag=hyprod-20&linkCode=df0&hvadid=167126942833&hvpos=1o2&hvnetw=g&hvrand=11725875702041684460&hvpone=&hvptwo=&hvqmt=&hvdev=m&hvdvcmdl=&hvlocint=&hvlocphy=9005779&hvtargid=pla-310404907374&psc=1 I use the black one the most. Some people in the reviews say they have trouble with them rolling, but I’ve never had an issue with this. These are the ones I would more strongly recommend.
