Opening Tool
The must-have tool for DIY stress balls! Easily holds your stress ball skin open so you can fill it with slime, beads, or charms without the mess. Perfect for making custom stress balls faster and easier.
Stress Ball Silicone Sealing Glue
The best glue I’ve found for sealing handmade stress balls!
Easy to use, smooth texture, and gentle on balloon skins—no heavy corrosion or stickiness. Perfect for creating durable, leak-proof stress balls.
This Silicone Sealing Glue is my absolute go-to for stress ball making!
✔️ Not too thick, making it super easy to apply.
✔️ Strong seal while staying gentle on the balloon material (helps avoid damage or corrosion).
✔️ Fast-drying and reliable for long-lasting stress balls.
⚠️ Please note:
Silicone glue has a noticeable smell, so I highly recommend using it in a well-ventilated space. Wearing a mask is also a good idea for extra comfort and safety.
Once you try it, you'll see why it’s my favorite for professional-quality stress balls!
Enjoy crafting your unique stress ball while staying safe and stress-free!
About this product
The Opening Tool is the essential accessory for DIY stress ball making by JoliSlime — a small tool that holds your balloon skin stretched open hands-free while you fill it with slime, beads, or charms. Without it, filling requires one hand to hold the skin open and one hand to pour, which makes precise filling messy and difficult. With the Opening Tool, the skin stays open and stable, allowing both hands to focus on filling cleanly and efficiently. Compatible with all JoliSlime balloon skin types: standard clear and cream skins, pomegranate-shaped skins, and the skins in the Build-Your-Ball Mega Kit and Trio Kit.
The Opening Tool is included in the Build-Your-Ball Mega Kit and available separately for customers who want to improve their DIY workflow or replace a lost tool. Particularly useful for heavy fills (block beads, ice cube charms, rice fills) where precise placement matters, and for younger makers who find the two-handed technique difficult to manage alone. Pairs with the Silicone Sealing Glue (sold separately) to complete the JoliSlime DIY toolkit — open with the tool, fill, tie or seal with the glue.
For DIY use. Recommended for ages 8 and up with adult supervision. Ships worldwide.
