“Shaker stickers” and “water stickers” whose contents move when shaken. While they have gained popularity for their cuteness, dedicated kits were not available, making them difficult to acquire.
Videos recreating these stickers using substitutes have garnered attention on social media, captivating children and adults alike with shaker stickers and water stickers.
We felt that many people were eagerly awaiting materials to create such original stickers.
Against this backdrop, MY mama Co., Ltd. will launch "Sheika," a dedicated material that allows anyone to easily make shaker stickers.
## To turn "difficult" into "fun"
Making shaker stickers required combining multiple materials, making it not something that could be easily enjoyed.
Furthermore, there were no dedicated products for water stickers containing liquid, making it a particularly high-barrier area for creation.
There were concerns on social media about leakage when trying to create them using substitutes like resin.
"It would be great if we could easily make not only shaker stickers but also water stickers."
With this in mind, the planning for "Sheika" began.
## Balancing "store-bought look" and "ease of creation"
We wanted the finished stickers to resemble commercially available products.
On the other hand, it needed to be designed so that anyone could easily make them.
Achieving this balance was the biggest challenge in the planning.
In particular, we designed it by meticulously anticipating the actual production process, including the width of the adhesive part, the thickness of the material, and the selection of materials to be used.
After repeated prototyping, we achieved a structure that combines ease of creation with strength.
As a result, a durable capsule was completed that would not collapse even if a weight of approximately 1kg was placed on it for a full day.
## Wide range of arrangements possible
"Sheika" is designed to accommodate various arrangements.
- Shaker stickers with enclosed parts
- Water stickers with liquid (※Slightly higher difficulty / Recommended for display and collection purposes)
- Original stickers with photos or snack packaging as backgrounds
- Decorative stickers utilizing leftover film
The biggest feature is that it can produce not only shaker stickers but also water stickers.
## "Complete with just this" set design
"With this kit, you can definitely make cute stickers."
Based on this concept, we paid close attention to the set contents.
By combining newly designed background stickers for sticker creation, "yumekawa" (dreamy cute) enclosed materials, and mini ribbons for accents, the set is configured to allow users to create high-quality works without worrying about material selection.
Through repeated prototyping and verification, we resolved each minor issue that emerged, resulting in a specification that even first-time users can tackle without hesitation.
## The series' sentiment embedded in the name
The product name was decided through an internal company competition.
Following "Hajiko" and "Pukkun," it is being developed as a familiar series that feels like a person's name.
Inspired by "shakashaka," it was named "Sheika" from "shaker."
## More freedom in sticker making
Anyone can make cute stickers without special skills.
"Sheika," which allows users to make not only shaker stickers but also water stickers (though with slightly higher difficulty), proposes a new way to enjoy crafts that has not existed before.
We will deliver the joy of creation and the satisfaction of completion to even more people.
