Here's a tote bag that's ready for all of your adventures. It’s fully reversible, so you’ve got options. Solid color on one side, printed on the other. Two bags in one. Wear the design on the outside, declaring your passion to the world, or flip it around for a quieter look. It’s built in the perfect proportions for a carry-all, so you can keep all the things you need inside the all the things you love. The zipper pocket on the solid side will keep your smaller things safe, and the shoulder straps are perfectly sized for over the shoulder or in-hand carry. Wear it on your next lecture, to the lab, or out in the field.

Recycled canvas is made with textile waste cuttings that are otherwise discarded as trash. Instead of filling up the landfill, these cuttings are collected and spun into yarn that is then woven into fabric that can be used again. You may notice some irregularities in the material, this is natural in recycled canvas, since the collected material varies in content.

The tote bag looks amazing online and even better in real life. I bought it as a gift and didn't want to give it away once I saw it in front of me. Great quality, good size, straps perfect length, .... And the design's just wonderful. The recipient really loved it too

I already had 2 other tote bags like this one but with different themes, I use them a lot so I knew this one would be perfect, the colours are bright and cheerful and it hold a lot without getting uncomfortable to carry around, a really good design!

Super good quality! Loved the print and the size of the bag, definitely recommended!

The bag is stunning. I bought the one with the botanical plants on it and I love the drawings of the plants. Also the colour mint green is beautiful. Very nice product!
S
I am a sucker for mushrooms. I find them so pretty and magical, and very very important for the ecossystem. There is something mesmerizing about them. And so I had to get one of these pretty tote bags, but it was hard to choose one. I went or the one that was more Autumny, and perhaps in the future I'll get another tote bag with mushrooms. The material is quite good and the print is lovely.

Great gift. Quality/function plus cool design that the gift receiver appreciated… or so they said. Think it bought me some social currency with them.

Very good strong product. Love the fabric, distribution and mix of flowers and insects and the blue. Beautiful.

Torba jest bardzo dobrze wykonana, pojemna. Ma piękny wzór. Polecam 😊
S
Lovely quality, sturdy and a fair bit bigger than expected (which is great!) I get lots of compliments on it & it matches my entomology mug + tea flask!
L
Cool-looking and sturdy, perfect for grocery and other shopping. I dislike grocery shopping, but being able to do it with such a nice bag shifts the whole experience from one of hunger-fueled resentment to one of grudging satisfaction at an annoying job well done. The bag fits more cheeses than I can actually carry. 11/11
E
Really happy with this purchase. Love the print and the fabric is good quality and the construction/sewing is very secure and well finished. The handles are the perfect length. The print is maybe not quite as clear as I anticipated, but this is due to the structure of the fabric and doesn´t detract from the design.
D
Good quality, the bag looks like in the pictures. It wouldn't be my last bag from your collection!
L
The perfect bag to all my stuff, when I travel around and teaches how to do the best possible EKG.

Hands down the highest quality lab notebook I've used. My only complaint is now I'm ruined for other lab notebooks forever.

Very pretty scarf
The scarf is light, the colours are vivid, and the print is very cool. Plants, skulls, and mushrooms; who can say no to those?

Very stylish
Lovely glass, stylish, great quality, lovely feel in the hand, enough weight but not too much. They wash well - I do by hand as don't trust my dishwasher! This is the fourth one I've bought as a gift. Would definitely buy again.

Stylish item
Lovely glass, great quality, very stylish. Bought as a gift. Had bought one before, decided to get three more as gifts. They are lovely as the designs are so different, and can be chosen for an individual.

Quality item
Gorgeous glass, so lovely to have stand out (theme personal to the person) glasses than can be used regularly. Bought as a gift. I bought one last year, went down really well, this year buying three!

i bought a couple of these glasses in Salt’s Mill and when I arrived home I knew I had to have more. They are beautifully weighted and feel lovely in the hand and the range of decorative styles is wonderful.
I now have a set of six and as someone who used to buy my glasses from charity shops its quite a change.

Love!
I have been collecting your drinking glasses through Outland in Norway. They do no longer have a lot of your items anymore, so I decided to purchase through your site. Well packaged glasses that made it without any damage. Wonderful products and great shipping. Will shop again :)
