I'm selling these because I used them when I was a student, but no longer need them. One is unused. The other has been used. It's paper tape with adhesive on one side. The adhesive is similar to the type found on the back of postage stamps. You use it by wetting the adhesive side with a water-soaked sponge or similar. 【Manufacturer】 MUZE 【Type】 Kraft paper, brown 2.5cm wide, 45m Comes in a zip-lock plastic bag 【Storage Instructions】 Keep away from moisture. Please seal it in the included plastic bag. We recommend storing it in a Tupperware-type container (round ones seem to be more airtight). To make it last longer, put it back in the plastic bag and Tupperware container frequently while working with it to minimize exposure to air. Please note that the actual color may differ slightly from the images due to the environment of the camera and receiving device. Please understand that these have been stored at home for a period of time before purchasing. Thank you for looking.
