I love these! I got the blue ones too and I’m going to keep getting more. I don’t use an STP so unfortunately I can’t speak on the functionality in that department. I do have a Pack and Play however, and oh boy. 10/10. So comfy and with a cute logo! And my girlfriends love them too!
I am using the packing gear regularly. I just cut the extra band for more comfortable while packing. I'm very happy. Thank you Axolom. It's really a good product.
