Case Study:35ml Roller Bottle With Silicone Case

How we break through customers’ customized requirements through technological improvements



In response to the evolving needs of our discerning clientele, we recognized a growing demand for larger capacity roller bottles in the market. While conventional options typically range from 5ml to 20ml, our astute customers sought a more spacious solution, specifically requesting a 35ml model.

Understanding the significance of brand identity, our clients expressed a desire to elevate their image through tailor-made features. To meet this demand, we introduced an array of customizable options, including a distinguished bamboo lid adorned with their logo. Furthermore, we offered a bespoke silicone case available in five vibrant hues, allowing our clients to showcase their brand personality with flair.

By aligning our product offerings with the precise requirements of our customers, we not only catered to their practical needs but also provided an avenue for them to express their brand ethos creatively.


The distinctive design requirements presented a series of obstacles, with a primary concern being the stability of the bottles upon the application of silicone sleeves. Given the slender profile of the bottles, maintaining an upright position proved to be a significant challenge once the sleeves were affixed.


Our team engineered a reinforced base for the bottles, enlarging the bottom apertures from 2mm to 12mm. This structural enhancement not only addressed the stability issue but also upheld the integrity of the design, allowing the bottles to stand with the silicone sleeves in place.
