Brand from Japan: OMD. A convenient all-in-one gel that fulfills the three roles of base, color and top.Easy to hold like a pen, easy to apply on your own nails, and compact for storage.Since the off is just peeling off, there is no need to use a remover such as acetone that puts a strain on the nails.In addition, it has almost no peculiar unpleasant odor and does not contain parabens or talc, so anyone can enjoy their nails with peace of mind.How to use:The handle is a dial type, and gel comes out from the tip when it is rotated.Remove excess oil and dirt from nails by hand washing or with an oil-removing solvent, then place an appropriate amount on clean nails and irradiate with UV/LED light to harden.The curing time varies depending on the light, so please irradiate until it is no longer sticky to the touch.Please note that if you apply too much at once, it may cause hardening failure. (Poor curing: The surface of the gel will shrink wrinkly, and the inside will be half-boiled.)Referen
