A good substitute for acrylic nails would be press-on nails or gel nails. Press-on nails are pre-designed artificial nails that can be easily applied and removed at home. They come in various sizes, shapes, and designs, offering a temporary and non-damaging alternative to acrylic nails. Gel nails, on the other hand, are applied with gel polish and cured under a UV or LED lamp. They provide a durable and long-lasting manicure without the need for acrylic extensions.
