Wedding or Event Favors
Fill with custom spices, teas, or bath salts; tie with a tag or ribbon for presentation.

Gift Packaging
Combine sets in recycled cardboard or bamboo boxes for an upscale, sustainable touch.
Small shops and food artisans often repurpose these spice tubes for sampler packs, promotional giveaways, or branded merch. A printed logo or tag turns a simple spice tube into an attractive product; perfect for farmers’ markets, culinary schools, or seasonal promotions.
Culinary Education & Marketing Uses
Culinary programs and artisan food producers alike can use 25×150 mm glass test tubes to teach portion control, ingredient preservation, and presentation design, skills essential for modern gastronomy. These tubes not only demonstrate measuring accuracy and aroma retention in class experiments but also double as eye-catching packaging for retail samples or tasting events.
Discipline
Learning Outcome
Example Activity
Culinary Education
Practise precise portioning, aroma evaluation, and ingredient preservation using small sealed sample containers.
Students prepare a flight of spice blends in test tubes and run a timed aroma/seasoning lab to compare sensory retention.
Food Science & Nutrition
Explore shelf-life variables, moisture control, and micro-packaging effects on volatile compounds and flavor stability.
Conduct a mini stability study: store identical spice samples under different conditions (light, temp, humidity) and record sensory/chemical changes.
Packaging & Retail Marketing
Design and test small-batch branded packaging concepts that balance aesthetics, usability, and sustainability for direct-to-consumer sales.
Create branded test-tube sample kits, add decals/labels, & perform A/B tests at a pop-up or farmers’ market to gauge buyer preference.

Exactly what I needed! Great quality test tubes and they arrived quickly. Ordered 300 of them, maybe 6-7 tubes were broken upon delivery. Glad I ordered more than I needed for that very reason. Otherwise, very happy with my purchase.

It' great that there is a place that sells this kind of stuff within Canada so the shipping was pretty fast and there was no customs fees.
Everything was packaged super carefully and no breakage occurred during transportation.
the actual test tubes themselves looked great however they were not all the same size. 27/100 of them were 1-2mm bigger in diameter.
The corks looked good but upon close inspection, they were not of the best quality of cork. There were huge holes and slits in some and they seemed really dry. Good quality corks cost about 20cents each and lasts about 7 years on the shelf and low quality corks cost 10cents and only last 1 year. I suspect these are the latter.
