Given the unbelievable popularity of the "Fifty Shades of Grey" novel, a line of related merchandise is perhaps inevitable. But what isn't so predictable is that the merchandise would be sold at mall stores frequented by teens and tweens.

Items based on the bondage-heavy novel are being sold at Icing, a jewelry and accessories store owned by Claire's. According to a Fox news report, those items include handcuff-themed bracelets and t-shirts with the phrase "Looking for Mr. Grey." Icing's collection also includes a classical-music CD with songs selected by "Fifty Shades" author E.L. James.

Claire's would not comment to a Fox news reporter on the issue, but emphasized on Facebook (FB) that the Icing stores are targeted to women over the age of 18. Claire's namesake stores cater to younger teens and girls.

Icing's Facebook page received dozens of comments on the issue. One user called the move "very poor taste and decorum," while another asked, "Why would you promote this to young teens who shop at your store?" Other users defended Icing, saying it is not a store for children.

Claire's isn't the first company to try and capitalize on the success of the erotic bestseller. Hotels around the country have debuted "Fifty Shades" packages, and there is a board game where players earn "inner goddess" tokens.

The book has even made its way into college courses. American University is offering a class based on the novel that promises to discuss sexuality, health, public relations and marketing.

But hotels and college courses are not normally the territory of teenagers. An inexpensive jewelry store at the mall that offers ear piercing, however, most certainly is. "That’s bananas to me," said Missy Suicide, founder of the Suicide Girls website, in an interview with New York Magazine. "If the mall store is selling bondage-lite accessories, that’s a different sort of world."

It's a world that some moms of teens and pre-teens aren't too comfortable with. The One Million Moms website is urging members to email Claire's and demand that the "Fifty Shades" line be removed. "Attempting to make sex and bondage cool and profiting by it is wrong when teenagers are frequently visiting the store," the website says. "Older teens may be their target market, but many tweens enter their stores and are influenced by these items as well."
