I bought these from ebay and they arrived today.

Although they feature the marketing (enormous fold out poster squished in there) of one of the sport's less niche (and ethically spotless) companies, they would seem to be exactly the same as my Rema Tip Top kit, the box is the same moulding but different colour, and the patches and sandpaper look identical. Only from this seller, three cost a smidge more than just one Rema kit. 😀
