They come in four different personalities, each designed with women in mind.
The Tennis Coach, for instance, is "sculpted and fit" and promises to "take very specific aim".
The Millionaire, on the other hand, is a "classic gentleman and an all-rounder" who is here to "pleasure you like the princess you are".
They are "personal massagers" - also known as vibrators - for women. Each comes in a different colour and is represented by a simple cartoon character.
Made by Swedish brand Smile Makers, which comes under the company Ramblin' Brands, these vibrators are the first to be sold by a major retail chain in Singapore.
Launched on Wednesday, they are exclusively available in health and beauty care store Watsons Singapore island-wide and its online store.
Not everyone was aware of what they are.
When shown the discreet package yesterday, a 57-year-old woman in Toa Payoh asked: "Is it perfume?"
When told that the box contains a vibrator, all she said was: "Oh." She then stared at the packaging for a few seconds, looking confused.
After the woman, who declined to be named, finally figured out what it does, she said it was not up to her to decide whether such vibrators should be sold in mainstream stores.
"It may be not okay for my generation, but it may be okay for the younger generation," she added.
Another woman, who wanted to be known as Lisa, told The New Paper the packaging looks like that of a children's toy.
But the 32-year-old did not oppose the sale of the vibrators in Watsons.
"It is okay to let people have a choice, like how condoms are displayed in public," said the mother of a five-year-old girl.
She does not think the sale of the vibrators will be a bad influence on teenagers.
"I wouldn't call it a danger. It is up to parents to explain to their children if they ask about it," she said.
Mr Walter Lim, 45, who has an 11-year-old boy, agreed the issue is not about where the vibrators are sold but rather about educating the young.
