Mens American Flag Stars and Stripes G-String

You say this is very stretchy so if you are between sizes does the small / medium fit better ?

Approx sizing per manufacturer is: G-string sizing Small-Medium fits 28" - 34", Large-XL fits 34"-42"

Is this item, NPT-SW105-Small-Medium MENS AMERICAN FLAG STARS AND STRIPES G-STRING the same as NDS-JF-9311-USA-FLAG-SM VALENTINO'S MENS G-STRING BY NDS WEAR? I purchased the NPT-SW105 in the past but it had different bands then the Valentino’s G-string. I prefer the thinner bands that are on the Valentino’s g-string and want to make sure that I don’t get the same exact ones again.

Dear Paul, These are not the same type of string on these items, The Valentine has a rounded small string and the Flags and Stars has a thin but flat string around it.
We hope this is of assistance. Thank you

does this come with a c ring?

No it does not, this is a Flag Gstring only.

This items is a 2 sizes item only due to the great fabric and stretch, so a Large would the the: Large-XL size you need to select. Hope this is of assistance.

I Available with the Canadian flag instead of the American flag as a theme

Hello, Unfortunately not in this style, however; we have a custom g-string that you can add and image on the front of it, it will not cover the entire G-string however very popular for personalizing and item, you can see that item with the link below:

How flimsy is this? There are a lot of lingerie/toy stores that sell these skimpy types of g's....and they all tend to be super flimsy and cheap....most of the old Calif. Muscle seemed to be strong and not super flimsy. thankx
