🛠️ Step-by-Step: How to Make It
1️⃣ Plan Your Fill
Visualize your texture (liquid-like, creamy, clay, jelly, crunchy?) and choose your combo.
2️⃣ Pre-Prep Your Mix
If you’re using slime or soft clay, let it sit overnight to reduce bubbles and improve texture.
3️⃣ Inject with Care
Use your syringe to fill the ball. Don’t overfill! Leave enough space to seal properly.
4️⃣ Seal It Up
Apply a thin layer of TPR glue at the neck. Wrap with plastic wrap and press gently. Secure with a zip tie. Let rest 24 hours before use.
5️⃣ Customize the Look
Decorate with stickers, glitter, or even embed mini characters for extra charm.
