Sheet masks are one of the easiest ways into Korean skincare: open a pouch, lay it on, relax for a few minutes. Round Lab's Mask-a-Day Hydration Bundle packs that habit into one box of 50 masks drawn from five different Round Lab lines. Below is what the brand says is inside, how you could rotate the masks through a week, and what to check before you order.
What Round Lab says about it
According to Round Lab, the bundle brings together five of its sheet masks, ten of each, for 50 masks in total. The brand lists the contents as:
- Soybean Nourishing Sheet Mask (10 pieces)
- 1025 Dokdo Water Gel Mask Sheet (10 pieces)
- Birch Moisturizing Sheet Mask (10 pieces)
- Pine Calming Cica Sheet Mask (10 pieces)
- Birch Moisturizing Double Gel Mask (10 pieces)
Round Lab describes the masks as designed to replenish, soothe and comfort skin with daily use. The signature ingredients it names are birch sap from Inje, deep sea water from Ulleungdo, a pine cica complex and fermented soybean. According to the brand, each mask delivers targeted moisture while supporting a healthier-looking skin barrier, and the set is meant for all skin types looking for a simple daily boost of hydration, radiance and soothing comfort.
The bundle is listed at $83.72 on Round Lab's US store at the time of writing, which works out to roughly $1.67 per mask. Prices and promotions change, so check the current price on the brand page.
Where it fits in a routine
In a typical Korean routine, a sheet mask goes after cleansing and toner and before your serum or cream: cleanse → toner → sheet mask → serum → cream, with sunscreen as the last step in the morning. Most people mask at night, when there is time to sit for a few minutes, then press the leftover essence into the skin and seal it with a moisturizer.
Because the box mixes five masks, one way to use it is as a weekly rotation that follows how Round Lab describes each line:
- Birch masks (two types) for moisture-focused nights
- 1025 Dokdo water gel mask for a mild, basic hydration night
- Pine Cica mask for evenings when you want a calming step
- Soybean mask for nights centred on barrier care
Who it might suit
Round Lab says the bundle is for all skin types. It looks most useful for people who already enjoy sheet masks and want variety without buying five separate boxes, for anyone trying to build a regular masking habit, and for K-beauty fans who want to sample several Round Lab lines in one go before committing to full-size toners or creams from a single line. The mixed box also makes sense as a gift.
If you only like one type of mask, a single-type pack is likely the better buy, since 40 of the 50 masks here would be other formulas.
What to check before you buy
- Ingredients: read the full ingredient list of each of the five masks on Round Lab's page, especially if you know you react to certain plant extracts.
- Patch test: try a new mask on a small area first, and stop using it if your skin feels uncomfortable.
- Storage: 50 masks is a lot. Check the expiry dates when the box arrives and plan how quickly you will use them.
- Shipping: Round Lab's US store may not ship everywhere. Check shipping to your country and any duties before ordering.
Our take
The Mask-a-Day Hydration Bundle is less about one hero formula and more about convenience: five Round Lab sheet masks, ten of each, in one box. If you like sheet masks and want an easy way to try the Birch, 1025 Dokdo, Pine Cica and Soybean lines side by side, it is a tidy way to do it. We have not used these masks ourselves, so compare the ingredient lists, check the current price and shipping, and patch test before making it a daily habit.
