It's shaped like a teardrop, it's pink and it helps apply makeup base with an ease!
This is called the Nippon Teardrop Sponge!
My AMW Workshop Series Part 3: Waterproofing Your Makeup participants were lucky! They each get to try the newest sponge from Nippon Esthetic, my to-go-to brand when it comes to professional tools!
Unlike regular round sponge, this is shaped like a teardrop with a wide base and a narrower tip. The teardrop shape makes base makeup application easier, I'll tell you why after the jump!
At least half an inch thick, this makes medium to heavy coverage base not only a "possibility" but a breeze! You may use this wet or dry depending on your coverage preference.
According to Nippon ---
The reusable sponge creates an even, flawless finish for any foundation formula. Washable with Nippon Pro Dual-Purpose Cleaner. Dermatologist tested + hypoallergenic. Instructions: Use the tip of the sponge for a precise application, and the wide end to spread foundation evenly.
