Chemical allergens emitted by pieces
We purchased three puzzles, two are versions of Van Gogh's Starry Night and Starry Night over the Rhone. The 3rd is Mt. Fuji (artist ?). The plastic container of one was cracked and in pieces when it arrived. All three puzzles have a strong and offensive chemical odor. We think it might be the printing ink (maybe uncured uv ink?). The smell rubs off on fingers requiring 95% isopropyl alcohol to remove. I took the puzzles onto the back porch to air out. Still waiting for the stink to abate. I may have to wait until summer when I can put them in the sun to bake them out and have the ultraviolet light finish curing them. I wore nitrile gloves to finish one outdoors to see if it would be worth doing the other two. Many people are sensitive to this type of chemical. The degree of difficulty is not great-maybe 3/5. Some of the edge pieces do not connect to their neighbors and not anchored properly to the adjacent inner layers well. The top layer of narrow features on 5 or 6 of the pieces had separated and flaked off. I noticed flakes through the ziplock packaging of the other two puzzles. The pieces aren't all separate when the package is first opened. The puzzles took several months to arrive. I can't recommend these puzzles. Too much of a hassle and not safe.
