Thank you for viewing! I am selling a set of 5 Clear Slider cases and 15 Tiny Fly-Shutter cases. I would like to dispose of these items quickly, so please refrain from negotiating for individual sales. The Clear Slider cases include the lid, lid lock parts, and separator, all complete. The Tiny Fly-Shutter cases include the lid, non-woven fabric for the lid, and the parts to secure it, all complete. If purchased new, the Clear Slider cases are approximately 800 yen each, and the Tiny Fly-Shutter cases are approximately 300 yen each. Including shipping, the total would be around 10,000 yen. I have bred a considerable number of domestic and foreign stag beetles and rhinoceros beetles. These cases were used during that time. They have been washed, but there may be insect bite marks, small scratches from washing, traces of management stickers, and stains on the non-woven fabric. I don't believe there are any cracks or chips, but please forgive any oversight. I do not sell items that are unusable. These would be suitable for beetle breeders or those who have unexpectedly increased their number of insects. As these are used items, please refrain from purchasing if you are looking for perfection or are overly concerned about minor imperfections. They will be wrapped in packing materials and shipped in a properly sized cardboard box. Thank you for your consideration. #StagBeetle #RhinocerosBeetle #Beetle #Insect #InsectCase #BreedingCase #Breed #Breeder #ClearSlider #FlyShutter #BulkSale
