More iphone cases, now with a 'line art' theme.
The first is "Gold Line" which is that complex drawing (always printed in yellow/gold ink) of a very geometric Green Hill like scene with Modern Sonic above it. Here, it's on a black background. The blue phone case has the "Emerald Club" fairly complex Sonic, Knuckles & Master Emerald line art in the center. The background for this case is a pattern of many smaller emeralds, so it's a little busy. They are nice cases with good use of the detail, but they're 35 dollars each...which seems a little pricey for something that's just a plastic case not an armor/bumper/gimmick case. This is a Sega Shop 2018 item

The Sega Shop can't seem to get enough of iphone cases, because in the gallary comes 8 more designs!
Maybe that's because each case costs 36 dollars...
The first is the 'patchwork' design seen on the notebooks, but this time with more patches including an Amy heart and 'Sonic speed' face. The second is classic with Sonic in the wing-ring on a blue checker background. The 3rd is an "Eggman Patchwork" but somehow the Eggman face is becoming a shark?
The fourth is more Sonic Forces 'bootcamp' theme where it's camo-pattern but with faces hidden in the swirls.

The next three are 'colorless motion', which means a thick-line work of a character, but with a highly-zoomed background image that's made of a small portion of a much larger size print of that character. (So, it is a background to itself) This design has been used on several other Sega Shop items, but it is interesting. The final case is a face-icon montage/pattern. It has classic siloutte faces for Sonic, Tails, Knuckles, Amy & Eggman, each in their own color but with white features. These are all 2018 items. (What happens when Apple lets out another phone, as they are prone to do fairly frequently? They seem to change where the features go so would the case become obsolete?)
