I bought 4 colours this time lavender, sky blue, baby pink and light orange from elastico series polymer clay. Out of 4 , three of them lavender, sky blue and baby pink were very brittle after baking and they were easily breakable. I baked them for 30 mins it was easily breakable, then I baked them for 60 mins even though it was broken. Very disappointed! Wish it was more durable.
