100% Cotton 650 GSM Luxury Spa Collection Towel Set

Cheaper on Amazon (plus free shipping).
Edit: $17.59 for “Denim” set, specifically, via link. Not sure about other colours.

Denim is the only one via 3rd party.

Light Blue is 18.49 at Amazon also.

Read the reviews about these towels on Amazon with the link provided in the first comment above. EVERYONE says that these towels are garbage. One person goes as far as to say that they do not even make good rags. STAY AWAY.
