Thank you for your interest in the product. [Product Description] This is a larval management sheet for 10 sheets (for 100 larvae). ...This was created as a hobby! I made too many, so I'm offering them to those who need them! ...If you change the mat frequently, you can add extra notes in the spare column! [Condition of the product] New, unused Due to printing errors, there may be some areas where the black lines are thick or thin. Since it's not a sticker, you'll need to attach it with tape or something similar! This was created as a hobby, so there are no returns, refunds, or warranties, but thank you for your understanding!
