Sticky - Material becomes very sticky on the surface. Materials might turn yellowish colour as well. Possibly due to oxidation, high temperature, high humidity and overly exposed to sunlight, causing sticky substances to surface out from the material itself. Patent/PVC leather and canvas are the most affected ones. Often, low quality replica bags are greatly facing this problem as well. This process is definitely irreversible (Stage 4 skin cancer).
Soiling - The single largest problem facing any thing. Dirt, dust, germs, your dead skin cells, dust mites, you name it, it is everywhere; & we guarantee it is on any of your belongings! Your bags won't kill you, but it does have the potential to make you very sick if you keep it on places where you eat. They stay in the pores of the leather, camp deep inside the canvas and travels frequently to practically anywhere with you! Researches say that you should think of your bag the same way you would a pair of shoes. "If you think about putting a pair of shoes on your lap, that's the same thing you're doing when you put your bag on your countertops"- your bag has gone where individuals before you have sneezed, coughed, spat, urinated, emptied bowels, etc!
