One of the number one questions I get asked by cart and kiosk retailers (and specialty leasing managers) is what the newest and most successful retail concepts are right now.

In addition to attending dozens of shows across the country to seek out trendy new products, we produce our own trade show, SPREE, specifically for the cart and kiosk industry. This year's show, SPREE Las Vegas, was a cornucopia of fun and new concepts for the industry. If you couldn't make it to the show, here are six interactive concepts worth checking out…

Bella Pierre—Wonderful line of mineral cosmetics. This is a perfect demonstration line with fantastic mark-up… and I love the quality of the products!

Wow Smile—Wow Smile has designed a beautiful kiosk to showcase their teeth whitening services, which is a growing concept for the industry. I love the higher price point and super low product cost.

My Design—Adorable rain boots for kids (and adults!) which you paint yourself (and it won't rub off in the rain). However, the design and colors can easily be changed when the consumer is ready for a new look. Terrific demonstration product that will attract all ages.

Ice Prints—Awesome new personalized concept where a digital image is fused permanently onto glass in seven minutes. This product could make up an entire cart by itself, or would be a great addition to any personalization or photo cart.

Miche Bag—Unique handbag concept that allows the consumer to achieve a new look by simply changing the exterior of your bag.

Onesole—Functional and fun line of women's sandals that enables the customer to interchange the top portion of the shoe for a new look. Perfect for traveling light!

Check back this week as I run down more exciting concepts from SPREE.
