VFLUO3M REFLECTIVE COLORS™, Universal adhesive DIY kit for Helmet/motorcycle/Scooter/Bike, 3M Technology™, 10 x 15 cm sheet, Red

My nephew received a Nintendo Labo kit for Christmas, but somehow managed to lose his pack of reflective strips that are used inside the models to bounce the IR signal around and make the thing work. We tried everything we could find in the local area at hardware stores to no avail.I stumbled across this pack on Amazon and from the product description, it seemed the white/silver pack would do the trick. The good news is, it does! My nephew was able to cut the strips down to match the size required for his Labo kit and they now work as intended. He's kept the spare for any future kits he gets. Hopefully he won't lose them again!

Not reflective at all! Totally useless!

I was looking for something to replace the Nintendo Labo stickers that reflect the IR sensor. When cut to the correct size they do the job perfectly

Not really as reflective as I would have liked.
