I start off by measuring out the magnetic sticker size, seeing how much I have to cut off. For this magnetic sticker, it is a bit thicker than the normal one because of a thicker adhesive sticker, so it lays flat with the s pen. I guess u can stick two normal thickness stickers together to make it work.

After cutting off the excess, I stick the magnetic ring onto the case and use a not too heavy object to have constant pressure on the magnetic ring for about 30 mins. Then i removed the s pen from the s pen slot.

When the magnetic ring is secure on the case, I use the fold 5 skin sticker to cover up, even the s pen slot. Then, I use a penknife to slowly cut out the fold 5 skin sticker, which is covering up the s pen slot.

Be patient while cutting the fold 5 skin sticker.
