I’ve not sold many paintings. However, for every individual paintings that I’ve gifted or sold in the past 2 years, they always come with a sturdy box to protect the paintings. The paintings will be wrapped nicely using glassine paper before they are placed into the box. Mainly because paintings dun react too much with glassine paper. I’ve seen some vids on YouTube that bubble wrapped paintings immediately but under heaty and humid weather like in Singapore, it might just not be appropriate enough. And for the upcoming art market, I’ve ‘upgraded’ the boxes a little by taking away the staplers 🙂
A little learning goes a further way.
