DEWEL Plastic Expanding Poster / Art / Document Storage Tube 24.5 to 40 inches Adjustable with Carrying Strap Waterproof and Light-resistance Telescoping Carrying Case (Black)

Sturdy

The construction is pretty flimsy. This is a tube in two parts. Though they lock together, the flexibility of the plastic tubes tends to eliminate the "lock" part of it. I haven't had the opportunity to test how waterproof it is, though the gaps between the two tubes suggests that exposure to light precipitation would probably be prevented, but if the case were to have water spilled on it, it might not.Overall, the product is what it claims to be. But when you purchase the least expensive, you get what you pay for.

I travel for Pearl Jam concerts and purchase posters from each show. They are usually 18 x 24”, but sometimes narrower, sometimes longer. Sometimes it’s outside and sometimes it rains. Sometimes I have a seat and can slide this tube under it, but more often it’s GA and I’m standing in the audience. Whatever the circumstance, this tube is da bomb dot com! Why, you ask? Well, it’s adjustable lengthwise per your needs. Has little round pegs and holes for you to set the length, and it stays in place. It’s durable - because it’s adjustable, it’s built like a tube that slides over another tube, so your stuff is well protected and doesn’t get bent. It’s hard plastic and the lid screws on tight, so it’s WATERPROOF! And the carrying strap is narrow and light (and also adjustable), so it’s easy to wear crossbody comfortably. Like for hours, comfortably. Like, it’s so comfortable that my husband OFFERS to carry it/wear it for me! Oh, and I have rolled up t-shirts I’ve bought and slid them in here too! I love this darn thing. (By the way, no one gave me anything or paid me to write this review. It cracks me up when I read those reviews and people are reviewing something they got for FREE. Ha! I paid full price for this sucker. No coupons, no discounts, no gift cards, no Amazon balance. Worth every cent.) Peace and love.

A bit more bulky than expected, but a perfect container to carry around large posters around, I normally carry around 36 x 48 posters for conferences and presentations and this is the perfect container for it

I used it to carry a research poster and it worked well. I love the option to expand or contract its size and the little piece on top to maybe add a name tag. Tip: Buy it in a color other than black for easier identification among the crowds
