Idk if the chemicals would be harmful to the geckos at all but you should be good if you let it air out long enough...
With that said i think it looks absolutely amazing. Better than alot of the stuff i see in stores. I especially like the use of the magnets. I would seriously consider selling these if i were you. Idk how long or how expensive they are to make but i could see myself paying $25-$30 for one if i had geckos lol. It really does look better quality than store bought ones!
