4. Langria Embossed Leatherette Jewelry Box

A girl’s jewelry collection can get really messy if left without a proper way to organize it. Earrings and other pieces of jewelry are bound to be lost or they will take a long time to be found. And that means longer wait time for the boyfriend when his girl is preparing herself for their date.

All that hassle and mess can be avoided with a single, most practical jewelry box that has a multiple-compartment design. One such jewelry box is the beautiful item from Langria that I’m showing you below. It has a sophisticated embossed leatherette exterior in lovely mint green, with a velvet lining interior that provides a soft touch — durable on the outside, soft on the inside. Inside the box are three vertical columns. The center column features a ring roll which is great for neatly placing rings, necklace pendants, and earrings. The left column is further split into two rows, these are great for any regular-sized jewelry. The right column is undivided free space, this is where bigger jewelry pieces will go.

Unique orthogonal design that has no sharp corners that could harm a girl’s delicate hands. The box is lockable which is a nice-to-have. Being a relatively small box, it is especially travel-friendly. When it’s not on travel, the box is best reserved for the most special pieces of jewelry. There are four different color variants available: minty green, pink, gray, and white.

2. Camkix 3-in-1 Lens Kit for Smart Phones

Does your girlfriend like to take pictures with her smartphone? Is she into taking selfies, wefies, food photos, or photos of other themes? If the answer is yes to any of those questions, she’ll love this versatile lens kit from Camkix.

This lens kit comes with three different lenses. Fisheye lens, macro lens, and wide-angle lens. With a macro lens, you can take close-up pictures, while wide-angle lens allows you to capture a wider area without having to move your position. The fisheye lens is something special, like the wide-angle lens, you can capture a much wider area, and at the same time, it does this hemispherical distortion on the image which is pretty cool. You can read more on fisheye lens on PetaPixel.

At slightly below $15 at the time of writing, this lens kit is a huge bargain. Especially since it also includes accessories like a universal clip, a carry pouch, and a microfiber cleaning cloth. There are other variants available: different colors and with or without LEDs for lighting control (the one that I’m showing here doesn’t have LEDs).
