Alternatively, you can diy using craft glitter and either clear or a pigmented from a set like Lavender Violet on Amazon. You can also make glitters and shimmers with microglitter and flakes. I recommend using black for switching your flakes to see the color you get if you end up with a clearing like I link below.

(I really like arte clavo liquids actually even though they're small. They're cheap, don't contaminate easily, have good staying power, activate strongly, and top beautifully.)
Warning: highly addictive.

Good for storing ones own powders: GPI Clear Plastic Reclosable Zip Poly Bags, Case of 100, 2-mil Thick, 2 Inch x 3 Inch, for Travel, Storage, Shipping https://a.co/d/igktmkS
Great for sprinkling and pour over recycling Dip Powder Recycling Tray System with Scoop, Nail Dip Container Portable Dipping Powder Storage Box with Soft Colorful Nail Dip Powder Brush for Nail Art and Makeup Tool https://a.co/d/h6ayw01
Cupcake liners are a must to recycle and find the best distribution of glitter to dip powder proportions.
Good luck!
