Check the tablet count first✔️ Korea Eundan Vitamin C 1000 comes in 600 tablets (20 months) or 120 tablets (4 months). Get the big jar for yourself, small ones to give away. MEGA DOSE C comes as 30 powder sticks with 6.4K+ reviews. Tablets and powder aren't liquids, so carry-on is fine. The jars are bulky; if you buy several, drop the outer boxes to save space.
