[Yao cosplay] Realm of Time's Wishes Purple Yao Version: Light Sheet Lost, Seeking Replacement Solutions

I am quite satisfied with the overall effect of this Yao cosplay in the Realm of Time's Wishes Purple Yao version from Honor of Kings, especially the glowing star accessory on the staff, which was originally the soul embellishment of this costume. However, while packing the props after taking photos, I wasn't paying attention and lost the light sheet. The star shell is still here, but without the light source, holding it in hand always feels like it's lacking a bit of ethereal aura. Over the past few days, I have searched all over Taobao and Xianyu to find an LED light sheet as an equal replacement, but after picking for a long time, I found that the common light sheets on the market either have the wrong size or their brightness and color temperature don't match the original. The original light sheet from this Miaowu Cosplay set emits a soft cool white light with even light transmission, and there are specific slots inside the star shell, so ordinary thin sheets easily loosen or leak light when stuffed inside. I've tried cutting it myself and tried using shrink plastic with LED beads, but the results weren't very ideal. So I wanted to ask the sisters who also bought this set before: does anyone know which supplier's light sheet Miaowu Cosplay used at that time? Or does anyone have experience with a successful DIY replacement? Actually, making cosplay props is just like this; many small accessories seem inconspicuous, but lacking them greatly compromises the overall sense of completeness. This time, to recreate Yao's agile feel, I put a lot of effort into the wig trimming, makeup color palette, and skirt layering. The purple gradient on the skirt and the white petal floating pieces were all fixed by hand piece by piece. The translucent material of the wings also underwent special treatment; after putting it on, coordinated with overhead lighting, it can present that dreamy refraction. Right now, the only bottleneck is this glowing star. If the light sheet can be replaced, this set of work can be considered truly complete. If any friends know the specific model or purchasing channels, please tell me in the comments section; I would be extremely grateful even for a close alternative solution. I usually study prop circuits myself, so if the size is confirmed, I could also solder a set of miniature SMD LEDs myself, but the key is that I haven't fully figured out the original light guide plate structure yet. All in all, I hope this call for help can get assistance from enthusiastic fellow fans, letting my Yao light up once again.
