Digital Monster - ver.1 Green - ver.2 Black - ver.3 Purple - ver.4 Clear Red Total: 4-piece set ※ These are not the re-release versions. These were released between 1997 and 1998. I obtained these as new, unopened items over 10 years ago. To prevent battery leakage, I immediately removed the batteries and stored them carefully in a dark place without using them. At that time, I checked for power and operation, and there were no problems with button contact or sound. The warning sticker "Do not put batteries in your mouth" is also included, and the items are in very good condition. I have opened the packaging to remove the batteries, so I'm listing them as "Like New". Currently, tape is holding the blister pack closed, so the photos are taken through the blister pack, but there are no errors in the above description, so I hope you can trust it. If anyone wants me to reopen the blister pack and add more photos, I will do so. Since I removed the batteries over 10 years ago, I don't remember if there was any leakage at that time, but these are very valuable items, and I recommend them to anyone who is looking for them! If you have any questions, please feel free to ask. Thank you very much.
