Oyumaru

Oyumaru: A temperature-dependent molding resin.

The colours are attractive and I thought it had more potential as sweets or fruits rather than as mold material.

To use Oyumaru:

1) Place Oyumaru into hot water above 80 degrees Celcius (a heat-proof container is recommended for this)
2) Wait around 5 minutes and remove Oyumaru with tweezers/chopsticks before shaping it into whatever you wish.
3 Allow Oyumaru to cool down and retain its shape.

Verdict: Very cute as jellybeans and jellies.
