I recently purchased this item, and it has been stored in a dark place in an unused condition. (I have opened and inspected it for the purpose of taking photos for the listing.) The thumb length is approximately 2cm. Please refrain from purchasing if you are concerned about any stains on the backing card, as there may be some from the time of purchase. *I am also selling multiple other nail tips, and I will offer a discount for combined purchases. Shipping will be via Rakuraku Mercari Bin (Nekoposu). (May be changed to Yuuyu Mercari Bin) I have pets. There is a possibility that pet hair may be attached to the product. I reuse packaging materials for shipping. Please refrain from purchasing if you are concerned about the above details, are sensitive to such issues, or are looking for a perfect product. Instant purchase is welcome without comments. Thank you. #NailTips #FalseNails
