it looks like its melting, leaving brown or black stains everywhere on the cheki 😢
seems like all of them, but it might be the material of the cheki holders I use (those books for business cards) so that plastic sheets could really help. definitely going to try that, thank you!
Could it be temperature? Is it hot where you store them?
I'm puzzled as what could be happening (and how to prevent it). It could be the type of pencil, but if it's all of them... Then it could be the environment. Humidity and heat are really bad for polaroids :S
