Yes, it is a sticker. :o I'll just see how he gets on with the markings on the mat. I've spent enough 😁
That is all top notch stuff - the oche that is included though is probably (95% sure) a sticker. For the ultimate set up the physical oche in my view is great - otherwise you are constantly checking where your toes are - here you just gently slide up to the oche and off you go. By no means essential - just really nice (in my view).
I bought the Target mat that was posted on here a few days ago from Amazon at £21.70 I think it was. https://www.amazon.co.uk/dp/B08P23X9XT?smid=A3P5ROKL5A1OLE And this is the dartboard + surround I ordered from Argos... another deal on here which I believe comes with an oche. argos.co.uk/product/7495759
Two more things i would recommend (should your son deserve it). One is a darts matt if you have a wooden floor and the best bit to go with it is a physical barrier as an oche (e.g WINMAU Sabre Oche). With those four things - my lockdown was made bearable. I even hit a 180 a month (from 2 in my entire life).
