If you already know you like gel masks, buying them one by one adds up. Round Lab sells its Birch Moisturizing Double Gel Mask as a 10-piece pack, listed at $25.20 on Round Lab's US store at the time of writing. This guide covers what Round Lab says about the mask, how ten masks could fit into a regular routine, and what to check before buying a multi-pack.

What Round Lab says about it

According to Round Lab, the Birch Moisturizing Double Gel Mask "delivers layered hydration and soothing comfort in a cooling hydrogel sheet." The brand says it is infused with birch sap from Inje, in South Korea's Gangwon Province, and that it replenishes moisture and minerals while calming signs of sensitivity.

It belongs to Round Lab's Birch line, which the brand builds around moisture. The pack contains 10 masks of the same type, so there is no mixing of different formulas to keep track of.

Where it fits in a routine

Masks are usually an add-on rather than a daily must-have. In the classic K-beauty order (cleanse, toner, serum, cream, sunscreen), a gel mask goes after toner, before or instead of your serum. With ten masks, you can plan them instead of using them at random:

Weekly ritual: one mask a week gives you roughly two and a half months of Sunday-night masking.
Busy weeks: keep a couple aside for long travel days, early schedules, or the night before an event.
Travel pouch: flat mask pouches pack easily, so a few can go in a toiletry bag for trips.

A simple evening order: cleanse, toner, mask (for the time printed on the package), pat in the leftover essence, then moisturizer. Follow the usage directions on the pouch or Round Lab's page.

Who it might suit

The 10-piece pack makes the most sense for people who:

have already tried a single Round Lab Birch gel mask and want more;
like a regular masking habit and prefer having a stock at home;
want to share masks with a friend or a sibling, or keep some as small gifts for a K-pop fan friend.

If you have never used this mask, Round Lab also sells it individually, which is a gentler way to start.

What to check before you buy

Do the math. At the time of writing, the 10-pack is listed at $25.20 and a single mask at $2.79 on Round Lab's US store, so the pack works out a little cheaper per mask. Prices change, so check the current numbers on the brand page.
Patch test. Before committing to ten masks, test the essence on a small patch of skin first.
Ingredients. Read the full ingredient list on Round Lab's page if you have known sensitivities.
Shipping and storage. Check whether Round Lab ships to your country and what it costs. Store masks as the package directs.

Our take

We have not tested this mask. Going by Round Lab's description, it is a cooling hydrogel mask with Inje birch sap, focused on moisture and comfort. The 10-piece pack is the practical pick if you mask regularly; if you are new to it, start with one. Either way, patch test and confirm price and shipping on the brand page.
