I bought its oil pastels came in long box purchased from local shop, and those pastels were working very well and I expected those won’t be waste and would stay longer, but I think they have been wasted, when I purchased them, they were like a chalk powder, now a days they are loke lipstick but not sticking to paper well.
So I think its age is completed. I couldn’t use it under 1 year.
The pastels are still with me but it seems that it is no use of me.
I think the shelf life of colours should be increased if they really weared out.
Packaging was best.
