Why combine Resin Clay and Foam Clay?
Resin Clay dries to a porcelain-hard finish and forms the smooth, rock-solid outer shell of the seal. Foam Clay as the core makes the charm significantly lighter without compromising stability. The 2:1 ratio is key: too much Foam Clay and the outer shell tears while shaping; too little and you lose the weight advantage. The result – a silky smooth, feather-light figure in Japanese wagashi style – simply isn't achievable with Resin Clay alone.

Materials & Tools
- Resin Clay (ratio 2)
- Foam Clay (ratio 1 – marble-sized amount)
- Black acrylic paint
- Bamboo skewer or needle tool
- Triangular stick or back of a craft knife
- Parchment paper as work surface
💡 Pro Tip: The Foam Clay core helps the seal dry more evenly and without cracks – Foam Clay releases moisture more slowly than pure Resin Clay. Once dry, optionally protect with a matte sealant.

❓ Frequently Asked Questions
Can you mix Resin Clay and Foam Clay together?
Yes – but we don't blend them into one uniform mass. Instead, we layer them: Foam Clay as a lightweight core, Resin Clay as the smooth outer shell in a 2:1 ratio. This way you get the best of both materials.
Will the charm stay soft or become hard?
The charm becomes rock hard – the silky smooth surface looks very soft visually, but it's as hard as porcelain once dry. The Foam Clay core only makes the seal lighter, not softer.
Can I make the seal using only Resin Clay?
Yes, pure Resin Clay works perfectly. The seal will be slightly heavier, but the technique stays identical – you simply skip the Foam Clay core step.
