Hi! Thank you for reaching out and for your purchase.
Regarding the files, I’m sorry for any confusion. Please note that for this specific set, I only provide versions with a solid black background—there are no transparent PNGs (alpha channel) available for this pack.
Since you're having trouble using them, a quick tip is to set the Blending Mode of the image layer to "Screen" or "Lighten" in your editing software (like Photoshop or similar tools). This will automatically hide the black background and keep only the design elements visible.
I hope this helps! Let me know if you have any other questions.
