Customer Reviews
Perfect for my 10mL Bac water kits instead of just having them inside the plastic containers.
Its the perfect size and is great quality.
I've gone through 3 different holders for my peptides, this one is by far the best one in terms of design and capacity.
Precision made perfect quality, surprise hinge and latch mechanism had me wondering how it was made. Elevates this practice to professional.
This is the most beautiful box by far. Thank you so much for making this box for me. This is my 3rd order and it won't be the last. Your customer service is outstanding and your products are amazing!! So glad I found you. Oh and thank you for the freebies. Love the caps!!!!!
Quality of work: Amazing, first quality!+
