Customers still waiting for Kim Zolciak's 'Kashmere' skincare

Real Housewives of Atlanta alum Kim Zolciak-Biermann loves posting pics of her family and kids to her Instagram account.

In May, the reality star posted a controversial image of her and her daughter, Brielle, teasing a then unannounced skincare collection .

A week or so later, she revealed Kashmere  -- described on the not-so-informative website as Kim's Body Renewal Spa System based on the unique combination of her favorite formulations, the Sugar Scrub and the Luxurious Skin Toning Oil.

The products come with a 30-day money back guarantee and a free candle, but other than inviting fans to make a reservation, there is no information on the actual ingredients in the products (which Zolciak-Biermann said she developed herself), what the products are supposed to do and exactly how much they cost.

The website promises the products will be available for purchase in 30-60 days and it isn't clear if the 30-60 days is being measured from when the products were announced or when you sign up for a reservation.

So when Zolciak-Biermann posted another image this weekend of her and Brielle doing a photo shoot for Kashmere, at least one customer had a question for her.

"Beautiful❤️❤️ Its been 6 weeks since you announced @kashmerekollections Do you have a date when it will be available for purchase for those of us who reserved"

The question went unanswered -- which naturally makes you wonder if the Kashmere two-step skincare system will have a similar outcome as other RHOA business ventures including:

...and the multitude of other products and services that were "launched" by current and former cast members from the RHOA's eight seasons on Bravo.
