Very very fast shipment…3 days…to Germany…😳👌👌👌
Pitkä toimitusaika. Paljon parempi laatu kun edellisillä tuotteilla jotka tilasin turbovolvon arvontaan
Sick awesome hoodie 🤩
Delivery was fast, packaging was proper, so the mug was safe. And it looked even better in reality than on the pictures when I ordered it. Many thanks and best regards from Estonia!
Like the quality of material is used.
Tämä L kokoinen oli oikein hyvä👍 yleensä kyllä käytän M kokoisia paitoja
The print and materials feel and look pretty good. For the price I am very surprised how good it is, I love it.
Laadukkaan olonen, hyvä väri. Toivotaan vielä boonuksenkin osuvan kohdalleen. ❤️🔥 Pasi.
