I wasn't aware that this is UV Resin instead of Epoxy resin (didn't know the difference till the teacher explained i.e. the timing that it takes to cure). So after knowing it is UV Resin, I felt that the pricing for the workshop despite 1-1 is still very expensive as the material is very cheap, and the UV resin is simply just some liquid that you squeeze onto the ready made acrylic coaster and than you cure it under the UV ray. I thought it was like able to prepare the resin from scratch to create a coaster like how epoxy resin coaster is prepared.
The experience was fun, teacher is kind, but not worth the price. I suggest the title of the workshop to indicate upfront that it is UV Resin Art Coaster and reduce the price.
