I did not knew in which category i should post this, but i was very interested in that, i could share some photos of the stuff (merchandise) with G4 that exist in our country. Sorry for my poor knowledge of english, and these ponies i have had mentioned are not mine. If moderators and admins will decide to delete this post, it is ok.
In our country we have various kinds of MLP stuff, starting from figurines either big or small, to coloring pages, books and puzzles. There is also school copybooks, and pencils with MLP, this kind of stuff is appeared to be more popular and widespread than any other. Some items you can buy in the small markets, and the others you could find only in special shops filled with toys for children. I went into the last one. I don`t know much about the stuff, so sorry, i would only post this.
I came across the new sets called `Guardians of Harmony` in which -
Spitfire and Soarin - Princess Celestia -Rainbow Dash and Tank - `Friendship is magic` Rarity Small Story set with Scootaloo and Sweetie Belle - `My little pony Fashems` with Twillight Sparkle and Fluttershy - Also, there was a `Rainbow Power` set with a big Rainbow Dash in it -  `Royal friendships` set with Twillight Sparkle and AppleJack (and Spike, plus some others items) - Set `Explore Equestria` with Friendship Express Train (and Twillight Sparkle) - `Friendship is magic` collection with Pinkie Pie`s Sweet Shoppe  (some outdated stuff)  - `Equestria Girls Minis Rainbow Dash School Pep Rally Set`  (my Rainbow ^^ dated 2016) - `My Little Pony - Painting AppleJack` (but not the set `Explore Equestria`, that`s weird?) - `Poppin' Pinkie Pie Game` (some outdated stuff) - Large Applejack plush -- `My little pony` AppleJack water cutie - `My little pony Musical set` - A puzzle with Rainbow Dash -
Books from G.M Berrow (translated onto russian) - Daring Do And The Marked Thief Of Marapore Media ,
Daring Do and  the Eternal Flower (also can be found in bookstore)  - Rainbow Dash and the Daring Do Double Dare -  Princess Luna and the festival of the Winter Moon -Fluttershy and the fine furry friends fair -  Coloring book (Fluttershy) - My little pony - pencils case (with TwillightSparkle) - Backpack My little Pony (with Princess Celestia) - About ponies in regular malls. They are made without Hasbro`s license and they are bootlegs. But their tags contains of various G4 and G3 MLP images.

The first one - (seven dollars)
Second - It`s tag with picture of G3 Rainbow Dash and Cheerilee - (note - at some bootleg`s tags you can also see names and titles like - `Fun lovely horse`, and even it`s logo reminds of Hasbro`s MLP!

Another items -
Sour fizzy candy with strawberry flavor. Also, inside of the pack is sticker with one pony. I`ve found Pinkie Pie and Luna

And another one puzzle -

A print with AppleJack (gold metallic) -

Blind bag figurine -
A puzzle four-in-one with marker, inside it we have glitter to add on a puzzle -

Small Twillight Sparkle plushie -

And another one, much bigger than previous - (she is a talking toy, by the way (it`s price is about 10 dollars))

That`s all stuff for now! =^_^=
